The four fineliners sit in our $ band (under $5 per pen) and the inks in $$ to $$$ ($5–75 per bottle). The Micron is #1 because Sakura sells its pigment ink as archival, and its eight sizes, from 0.15 to 0.70 mm, cover most line work in our $ band. - **Best overall pen:** [Sakura Pigma Micron](https://stationerytimes.com/guides/sakura-pigma-micron/). *Why it's here:* archival pigment ink in eight sizes, 003 to 12 (0.15 to 0.70 mm lines), in our $ band; made in Japan. - **Best for marker artists:** [Copic Multiliner](https://stationerytimes.com/guides/copic-multiliner/). *Why it's here:* Copic sells its ink as resisting alcohol markers, for marker artists; Copic Japan ended shipments in October 2026, so buy the refillable Multiliner Plus going forward. - **Finest line:** [uni PIN](https://stationerytimes.com/guides/uni-pin-fineliner/). *Why it's here:* the finest line here, 0.03 mm, in 13 widths up to 1.2 mm plus brush and chisel tips. - **Best for rulers and templates:** [STAEDTLER pigment liner 308](https://stationerytimes.com/guides/staedtler-pigment-liner-308/). *Why it's here:* a long metal tip for rulers and templates, in 12 widths from 0.05 to 1.2 mm, made in Germany. - **Best certified document ink:** [De Atramentis Document Black](https://stationerytimes.com/guides/de-atramentis-document-black/). *Why it's here:* the only ink here that meets the ISO 12757-2 document standard; 45 ml at €19.90 (about US$22). - **Best pigment black for Japanese pens:** [Platinum Carbon Black](https://stationerytimes.com/guides/platinum-carbon-black-ink/). *Why it's here:* the standard pigment black, also sold in SPC-200 cartridges for Platinum pens; 60 ml at ¥2,750 (about US$17). - **Best value bottle:** [Noodler's Black](https://stationerytimes.com/guides/noodlers-black-ink/). *Why it's here:* the biggest bottle here, 3 oz (about 88 ml) of bulletproof ink, handmade in the USA. - **Smoothest pigment ink:** [Sailor Kiwa-guro](https://stationerytimes.com/guides/sailor-kiwa-guro/). *Why it's here:* ultra-fine pigment that Sailor says resists feathering and bleed-through, for a smoother pigment ink; 50 ml at ¥2,530 (about US$16). ## How did we choose these picks? **We compiled these picks from published sources, not hands-on testing: makers' ink claims and certifications, published water tests, US availability and price band.** We counted only pigment or reactive inks that survive a wash once dry, then chose one pen or ink per job. ## How do the waterproof pens and inks compare? **The fineliners are disposable and cheap; the bottled inks cost more but fill any fountain pen.** Figures come from each product's guide. | | Pigma Micron | Copic Multiliner | uni PIN | pigment liner 308 | De Atramentis Document Black | Platinum Carbon Black | Noodler's Black | Sailor Kiwa-guro | |---|---|---|---|---|---|---|---|---| | Form | Fineliner | Fineliner | Fineliner | Fineliner | Bottled ink | Bottled ink, cartridges | Bottled ink | Bottled ink, cartridges | | Ink | Pigment | Pigment, alcohol-proof | Pigment | Pigment, document-proof | Pigment, ISO 12757-2 | Pigment | Cellulose-reactive dye | Ultra-fine pigment | | Widths or volume | 0.15 to 0.70 mm (8 sizes) | 0.03 to 1.0 mm (7 black) | 0.03 to 1.2 mm (13) | 0.05 to 1.2 mm (12) | 45 ml | 60 ml | 3 oz (about 88 ml) | 50 ml | | Dry time (published tests) | Not published | Not published | Not published | Not published | Over 30 s | 60 s | 50 s | 40 s touch, 100 s smear-free | | Made in | Japan | Japan | Not stated | Germany | Germany | Japan | United States | Japan | | List price | Not published | Not published | Not published | Not published | €19.90 (about US$22) | ¥2,750 (about US$17) | Not published | ¥2,530 (about US$16) | | Band | $ (under $5) | $ | $ | $ | $$$ ($20–75) | $$$ | $$ ($5–20) | $$$ | ## What makes an ink waterproof? **Pigment particles that bond to paper fibers, or a dye that reacts with cellulose.** Ordinary fountain pen and gel inks use dyes dissolved in water, so water redissolves the line. Pigment inks suspend solid particles that lock into the paper and stay put. Noodler's Black takes a third route: a dye that reacts chemically with cellulose, so it is permanent on plain paper but not on coated stock. The trade-off is maintenance. Pigment fountain pen inks clog a pen that sits unused, which is why Platinum, Sailor and Goulet all advise regular cleaning. Disposable pigment fineliners sidestep the problem. ## Should you buy a pigment fineliner or a waterproof fountain pen ink? **A fineliner for fixed-width line work; an ink if you already own a fountain pen.** A Pigma Micron 01 writes one 0.25 mm line every time, dries quickly because the tip lays down so little ink, and costs under $5. A bottle of Carbon Black costs more up front but refills a pen for years and gives a line that varies with pressure and nib. Fountain pen users who want the least risk should start with De Atramentis Document Black, which the maker says suits all fountain pens, or run pigment ink only in a pen they write with daily. See our guide to [fountain pens under $100](https://stationerytimes.com/guides/best-fountain-pens-under-100/) for cheap pens to dedicate to pigment ink. ## Which waterproof pen or ink should you choose? **Match the product to the job.** - **Sketching for watercolor:** Pigma Micron or pigment liner 308, then De Atramentis Document Black in a fountain pen. - **Coloring with alcohol markers:** Copic Multiliner Plus, the refillable successor to the Multiliner. - **Technical drawing with rulers:** pigment liner 308, whose long metal tip clears the ruler edge. - **Very fine lines:** uni PIN 0.03 or Multiliner 0.03. - **Signing and addressing envelopes:** Platinum Carbon Black or Sailor Kiwa-guro in a fine Japanese nib. - **Most ink per dollar:** Noodler's Black, 3 oz in our $$ band. ## Where are these waterproof pens and inks made? **Japan for five of the eight, Germany for two and the United States for one.** Sakura, Copic, Platinum and Sailor are Japanese makers whose pages or retailers give Japan; STAEDTLER prints Made in Germany on the pigment liner 308 and De Atramentis makes its inks in Germany; Noodler's hand-fills its bottles in the USA. Mitsubishi Pencil doesn't state a country for the uni PIN on the pages we read. ## Frequently asked questions ### What pen is truly waterproof? A pigment fineliner. Sakura calls Pigma Micron ink waterproof and fade resistant, STAEDTLER calls the pigment liner 308 waterproof on paper and document-proof, and Copic's Multiliner ink resists water and alcohol markers. Pigment particles bond to the paper fibers, unlike dye, which redissolves. ### What is the best waterproof fountain pen ink? De Atramentis Document Black if you want a certified document ink: it meets ISO 12757-2 and takes watercolor washes. Platinum Carbon Black is the standard pigment black with a high water-resistance rating in Mountain of Ink's test, and Sailor Kiwa-guro the finest-particle pigment for smooth flow. ### Is Pigma Micron ink archival? Sakura says yes: Pigma ink is a water-based pigment ink that is waterproof, fade resistant and chemically stable once dry, introduced in 1982 as the first water-based pigment marker. Archival means it should not fade or bleed over decades on acid-free paper. ### Can waterproof ink ruin a fountain pen? Pigment ink can clog a pen left unused, because the particles dry in the feed. Goulet advises cleaning a pen running Platinum Carbon Black weekly, and Sailor gives the same advice for Kiwa-guro. Noodler's Black is a cellulose-reactive dye ink, so it is less prone to clogging but still needs a rinse between fills. ### What is the finest waterproof pen? The uni PIN 0.03 and Copic Multiliner 0.03, whose 0.03 mm sizes write finer than the Pigma Micron 003 at 0.15 mm. The STAEDTLER pigment liner 308 starts at 0.05 mm. ### How long does waterproof ink take to dry? Longer than ordinary ink. Published tests put Platinum Carbon Black at 60 seconds, Noodler's Black at 50, Sailor Kiwa-guro at 40 seconds to the touch and 100 before it stops smearing, and De Atramentis Document Black over 30. Pigment fineliners dry faster because they lay down far less ink. ### Is Noodler's Black bulletproof ink waterproof? Noodler's says Black resists water, bleach and UV light once dry on cellulose paper, which it calls bulletproof. It works by bonding to the paper rather than by pigment, so on coated or synthetic paper the claim does not hold. ### Which waterproof pen is best for watercolor sketching? The Pigma Micron or pigment liner 308 for line work that will take a wash, or a fountain pen filled with De Atramentis Document Black or Platinum Carbon Black for a variable line. Let the ink dry at least a minute before painting over pigment fountain pen ink. ## Sources - [ピグマ (Sakura Japan Pigma page: 1982, the first water-based pigment marker; reference line widths by size)](https://www.craypas.com/products/regular/pigma/) - [コピック マルチライナー各種 出荷終了のお知らせ (Copic Japan, October 15, 2026: domestic Multiliner shipments end in late October 2026; the Multiliner Plus, sold since July 2026, is the replacement)](https://copic.jp/news/information/20261015/) - [uni-ball (US): PIN Fineliner Drawing Pens (13 line widths from 0.03 to 1.2 mm, brush and chisel, fade-proof and water-resistant pigment ink)](https://www.unibrands.co/products/pin-fineliner-drawing-pens) - [STAEDTLER (Germany): pigment liner 308 Fineliner (product information, 12 widths plus chisel, document-proof, Made in Germany; read in German)](https://www.staedtler.com/de/de/produkte/malen/fineliner/pigment-liner-308-fineliner-m308/) - [De Atramentis (Germany): Dokumenten Tinte SCHWARZ (45 ml, ISO 12757-2, suits all fountain pens, Art.-Nr. 1080, €19.90; read October 22, 2026)](https://www.de-atramentis.com/de/dokumententinte--2509.html) - [プラチナ万年筆: カーボンインク 万年筆用水性顔料インク INKC-1500 (Platinum Japan: 60 ml, ¥2,750, water-based pigment, W57 × 57 × H63 mm, 178 g)](https://www.platinum-pen.co.jp/products/ink/6848/) - [Mountain of Ink: Platinum Carbon Black review (60 second dry time, high water resistance)](https://mountainofink.com/blog/platinum-carbon-black) - [Noodler's Ink: 19001 Black (3 oz; archival, bulletproof, forge resistant, water resistant)](https://noodlersink.com/product/19001-black/) - [セーラー万年筆: 万年筆用ボトルインク 極黒（きわぐろ）13-2002-220 (Sailor Japan: ultra-fine pigment, 50 ml, W53 × D44 × H70 mm, about 203 g, ¥2,530; read October 21, 2026)](https://sailor.co.jp/product/13-2002/) - [Goulet Pens: De Atramentis Document Black (dry time over 30 seconds, water test)](https://www.gouletpens.com/products/de-atramentis-document-black-45ml-bottled-ink)
