P.W. Akkerman has been in the pen and ink retail business since 1910. Based in Den Haag, Netherlands, they also have a branch in Amsterdam. The iconic 60ml Akkerman ink bottle is both functional and stylish, and it reinforces the experience behind the brand. Diamine is their ink maker, but the design and aesthetics are all Akkerman. They offer a wide range of standard inks, several special editions, and the Dutch Masters series, which come in an even larger, 120ml bottle!
