I have a GL Trident with one of those super sparkly stamps (idk what they're called...stamp is made of a bunch of tiny sparkly squares, if u no what I mean). Anyways, these stamps are tougher to get off than a normal stamp. It came off fine but took some elbow grease.
Fun fact - those stamps also seem impervious to SC / detergent and other things that dissolve other, easier-to-remove stamps. It's hard to see on this one bc of the colors, but this stamp was not affected at all by a SC dye:
