I have used Diamine inks for a while now, and have been starting to get shimmer inks for holiday greeting cards. As I send them for multiple holidays, it's nice to have a bit of a variety. This is a rich purple ink, with an amazing amount of gold shimmer. It's not a water resistant ink in the least, but many aren't, so this is not a big deal. Diamine seems to have gotten the "low maintenance" end of fountain pen ink right. Cleans up easily with just water, and to date I've not had any problems with the glitter plugging things up in the pens I've used.
