Noodler's bulletproof ink 90 ml, Aircorp Blue-Black

Hand-mixed archival ink from the small American company Noodler’s has much to offer besides its steel-blue colour.

Its “bulletproof” nature is particularly noteworthy – it is 100% resistant to water, UV light, bleach and alcohol. To be truly bulletproof, the ink contains special cellulose-reactive dyes, which unfortunately make it unsuitable for writing on recycled paper and paper without a cellulose coating in general (it may feather a little).

Any other material, however, is easy for it. It also dries very quickly and is permanent, so you need not worry about smudged notebooks and can be sure that what you write will last forever!

It is suitable for new and vintage fountain pens and for painting.
