What is the Colorverse Colorvent Calendar 2026?
It’s the 2026 ink advent calendar from Colorverse, a Korean fountain pen ink brand: 24 doors, each with a new ink in a 15 ml glass bottle. Colorverse’s Korean page sells it as a limited edition and frames this year’s theme as “the colours of a deeper universe”, in keeping with the brand’s space-named inks.
Every colour is new. JetPens says the inks are dye-based, and Goulet says they run from standard inks to sheening and shimmering ones, without naming them so the doors stay a surprise. For the British alternative, with 25 inks and a bonus door, see the Diamine Inkvent Calendar 2026.
What’s inside the 2026 Colorvent?
Twenty-four 15 ml bottles, three colouring sheets and a VIP coupon pack, plus a golden ticket in a few boxes. Colorverse’s Korean page lists the contents; each bottle sits behind a door with a small card naming the colour.
3 colouring sheets, 23 × 19.8 cm (9.1 × 7.8 in); VIP coupons (20%, 10%, 5% off and free shipping, for Colorverse’s store)

360 ml in 24 bottles, a little more than five 65 ml bottles.
What is the golden ticket?
A ticket in 30 of the calendars that wins a Colorverse Premium Gift Set, redeemable until January 31, 2027. Colorverse’s Korean page values the set at ₩300,000 (about US$226).
The set includes four 15 ml bottles of 2027 special inks, Colorverse’s Shuttle dip nib in brass with a long black holder, an “ink barrel”, a Nebula Hubble notebook, and 100 ml bottles of Colorverse’s HIR and Pen Soap. Yoseka’s US listing says five golden tickets, so we use the maker’s figure of 30.
How does the Top 3 vote work?
Buyers scan a QR code on the back of the box, or visit Colorverse’s site, and vote for their favourite inks. Colorverse then releases the three most popular in larger bottles; Goulet says the 2026 winners will be regular editions in 2027.
The 2025 calendar’s winners show how it works: JetPens sells Erebus Crater, a 2025 Top 3 ink, in a 65 ml bottle.
How much does it cost, and where can you buy it?
It’s in our $$$$ band in the US, over $75. On October 22, 2026, Colorverse’s Korean store listed it at ₩198,000 (about US$149), and showed it sold out.
US sellers include Goulet Pens, JetPens, Yoseka, Goldspot, The Gentleman Stationer and Dick Blick, which calls it the Cosmic calendar. When we checked, JetPens had sold out and said it would not restock, and The Gentleman Stationer listed it as backordered.
Is it a good gift?
Yes, for someone who already fills a pen from a bottle. A 15 ml bottle is enough for about 18 fills of a 0.8 ml LAMY Z28 converter, so each colour gets a fair trial.
In South Korea. Yoseka Stationery’s listing says “Made in South Korea” and The Gentleman Stationer’s says “Made in Korea”.
Colorverse’s stores are run by PLNBEE, a Korean company, which sells the calendar on both a Korean and an international site.
Frequently asked questions
How much ink is in the Colorvent 2026?
360 ml: 24 glass bottles of 15 ml each. That's a little more than five of Colorverse's 65 ml bottles.
Are the Colorvent inks waterproof?
No. JetPens lists the 2026 inks as dye-based and not water-resistant. Goulet says the set runs from standard inks to sheening and shimmering ones.
How many golden tickets are in the 2026 Colorvent?
Colorverse's Korean page says 30 calendars hold one, each redeemable by January 31, 2027 for a Premium Gift Set it values at ₩300,000 (about US$226). Yoseka's US listing says five, so we go with the maker's figure.
Can you buy Colorvent inks separately later?
Only the three most popular, after a vote. Colorverse releases them in larger bottles the following year; the 2025 calendar's Top 3 came back as 65 ml bottles.
Is the Colorvent 2026 still in stock?
It sold out quickly. On October 22, 2026, JetPens and Colorverse's own stores showed it sold out, while The Gentleman Stationer listed it as backordered.
Does the Colorvent come with a pen?
No. It holds ink, three colouring sheets and a coupon pack, so the person you give it to needs a fountain pen or dip pen.
Is the Colorvent made in Korea?
Yes. US retailers Yoseka Stationery and The Gentleman Stationer list it as made in Korea, where Colorverse is based.
