Anyone here have experience with Diamine Forever series of permanent inks? I'm kinda interested in Skyline, Coral Blaze and Tiger Lilly colours, they resemble my favs of KWZ Grapefruit and Turquoise. But Grapefruit in particular is so weak against water.

My questions mainly are:

- Are they really as waterproof as those youtube vids show them to be?
- Do they clog fountain pens? Are they high maintenance?
- Anything to be mindful of? Any pitfalls?
