  • Colors: names per Komamono Lab (Japanese): Fonte brand page, checked November 2, 2026. The five names are the tip colors on Komamono Lab's Fonte page, romanized from its katakana. Tints were sampled from its lineup photo, where each pen has a clear body and a colored glass tip. Yoseka's photo for its listing shows a clear glass tip, so check which tip a shop ships.

What is the Fonte Glass Pen?

It is a dip pen with a colored glass tip on a clear plastic body. Komamono Lab, the original-goods brand of Japanese publisher distributor Nippan, sells it under its Fonte line of customizable pens. You dip the tip in ink and write, then rinse it for the next color.

Fonte is better known for a skeleton fountain pen with swappable caps. Yoseka Stationery says Fonte was first released in February 2019 and gained fans as a starter fountain pen; the glass tip is one of several tip options Nippan added later, with brush and rollerball. We couldn’t find a maker notice with the glass pen’s own release date, so we don’t state one.

Sizes, materials and prices are from Komamono Lab’s Japanese Fonte page; the cap and dip-only notes are from Yoseka’s listing, both read November 2, 2026. Komamono Lab doesn’t publish a weight or tip width.

Which tip colors are there?

Five, named for gemstones. Komamono Lab lists Rose Quartz Pink, Kunzite Purple, Citrine Yellow, Verdelite Green and Shungite Black on the page for the glass pen body. Its lineup photo shows a clear barrel with a silver-tone collar and the tint in the glass tip alone.

Yoseka’s listing photo shows a clear, uncolored tip. We can’t tell from the pages whether Yoseka ships the colored tips, so read the listing before you order a particular color.

How does it differ from Fonte’s other pens?

Only the tip: Fonte sells the same pen family with a glass, brush, rollerball or fountain tip. Komamono Lab’s page also lists a small round glass pen and a fountain pen with a converter.

Fonte pen Tip Size (Komamono Lab) Price in Japan with tax
Glass Pen body Colored glass, dip 13 × 117 mm ¥880 (about US$5.60)
Mini Glass Pen Glass, with a glass pen rest 13 × 90 mm ¥1,980 (about US$13)
biiro fountain pen Stainless steel, EF, converter included 14 × 121 mm ¥2,178 (about US$14)

Both glass models are dip-only. The biiro is the one to buy if you want to fill a pen from a bottle. Our guides to the Fonte Skeleton Fountain Pen, the Fonte biiro and Fonte Bottle Ink cover those.

Who is the Fonte Glass Pen for?

It is a cheap first glass pen for someone who wants to try dip pens before spending more. The body costs ¥880 (about US$5.60) with tax in Japan, and there is no cartridge or converter to buy.

  • First pen: a dip pen needs only a bottle of ink.

Skip it if you want a pen you can fill: Yoseka says the glass pen is dip only. If you want a nib that also works as a fountain pen, see our Pilot iro-utsushi guide, and for other starters our best dip pens for beginners.

How do you use a glass dip pen?

Dip the tip, let the grooves hold the ink, write, then rinse. A glass tip holds ink in its ridges and writes a smooth line until it runs dry, which is why the pen suits trying many inks. Wipe or rinse it before switching colors.

Glass is breakable, so keep the cap on when the pen is in a bag.

Where is the Fonte Glass Pen made?

Komamono Lab doesn’t say. Its Fonte page lists the size, materials and price but not the country of manufacture, and Yoseka’s listing doesn’t either. Nippan, its owner, is a Japanese company.

How much does the Fonte Glass Pen cost?

It sits in our $$ band ($5–20). Komamono Lab lists the body at ¥800 (about US$5) before tax and ¥880 (about US$5.60) with tax. On November 2, 2026, Yoseka Stationery listed it at US$9.

Caps are sold separately, so a pen with a favorite cap costs more than the body alone.

Frequently asked questions

Can you fill a Fonte glass pen with ink?

No. Yoseka Stationery says the glass pen is for dipping only and can't be filled with ink. Fonte's separate skeleton fountain pen is the one with a converter.

Does the Fonte Glass Pen come with a cap?

Yoseka says the body comes with a simple cap that protects the tip, and that a separate cap in more colors is sold on its own. Komamono Lab's page is built around choosing your own cap.

What colors are the Fonte glass tips?

Komamono Lab lists five: Rose Quartz Pink, Kunzite Purple, Citrine Yellow, Verdelite Green and Shungite Black. Yoseka's photo shows a clear tip, so confirm the color before you order.

How big is the Fonte Glass Pen?

Komamono Lab gives a maximum diameter of 13 mm and a height of 117 mm for the body. It doesn't say whether the height includes the tip or cap.

Is the Fonte Glass Pen fragile?

It is a glass tip on a plastic body, so a drop onto a hard floor can chip it. Keep the cap on in a pencil case. We haven't tested ours yet.

What does Fonte mean?

Komamono Lab says Fonte is Italian for a spring, as in water welling up, chosen to suggest ink flowing from the nib.

How much is the Fonte Glass Pen in the US?

Yoseka Stationery listed the body at US$9 on November 2, 2026, which sits in our $$ band ($5–20). In Japan the maker lists ¥880 (about US$5.60) with tax.
