So like the title says, I'm looking for a certain kind of sticker material, the textured kind from Mefferts that is on the Vulcano and, if I'm correct, originally on the stickered Skewbs as well (and I think the Pyraminx? But I may be wrong). I know this kind of material was originally on the Mini Pyramorphix but less fluorescent than the Vulcano. It's probably used on other Mefferts puzzles too but not that I have. Anyone know what kind I'm talking about? And where I might be able to procure some? Thanks.
