P.W. Akkerman launched his own ink line in 2010 to celebrate the 100th anniversary of P.W. Akkerman the Hague in the Netherlands. I could not find any information about where the ink is actually made. Here are swabs for all of the Akkerman inks I have reviewed so far. If you click on the swab it will take you to the review of that ink. I will update this page every time I review an Akkerman ink. For this brand, I'm going to organize them by number rather than collection or color.
