A fool proof solution

I've got quite a lot of ink related questions lately since I started using the permanent ink from Noodles. It seems to work nicely in my fountain pen no sign of clogging, even though the thought of steel nibs is nice they are not very practical not when you choose to draw no vertically. Hopefully this drawing might show some of the advantage of going water proof. The Ink was not available in Sweden (it's a small unimportant country on the rim of civilisation) so I ordered the ink from USA, the transportation of the ink was more expensive than the ink. Do anyone know of a place in Europe where they have it?
