Description The Diamine Ink Cartridges bring simplicity, reliability and a burst of vibrant colour to your fountain pen experience. Designed to appeal to both newcomers and seasoned pen users, these cartridges allow quick, clean refills without the fuss of bottles. Standard International Short Format These cartridges conform to the universal “short international” standard, measuring about 38 mm in length and roughly 7 mm in diameter. They fit into most cartridge-converter fountain pens with ease. Wide Colour Range Available in over 30 shades — from classic blues and blacks to bold pigments like emerald green, oxblood, and sapphire — the selection ensures your writing stands out. Easy, Mess-Free Refilling Simply insert a cartridge into your pen’s feed until it clicks. The ink flows quickly, allowing you to write within moments. There’s no mess, no syringes, and no soaking systems to worry about. Bright Dye-Based Ink Diamine’s ink formula is water-based and dye-driven, offering vivid saturation and smooth flow. It is not designed to be water-resistant, so avoid exposure to moisture for archival writing. Convenient Pack Sizes Generally offered in packs of 6 or 18 cartridges, these sets allow you to stock up and swap colours without running out mid-session. With dependable build quality and a spectrum of expressive colours, Diamine Ink Cartridges offer a practical and beautiful refill solution for any pen user’s toolset.
