It’s a little wet in a TWSBI Eco Fine Nib, but I’ll try it with different pens to see the best fit. It’s very similar to De Atramentis Document Blue, but I’d choose this for the better color saturation. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/654844646-octopus-write-and-draw-ink-414-blue-koi-waterproof-ink](https://www.desertcart.co.uk/products/654844646-octopus-write-and-draw-ink-414-blue-koi-waterproof-ink) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-08*
