210-piece Mixed Pack of Discs (15mm x 4mm) - 21 different colors!

These mixed packs of 15mm discs contain 10 of each of the 21 colors. They are 4mm thick.

Planning on using these with 15mm stickers? It has been brought to our attention that these are a little small for that purpose. Normally you would use a slightly larger disc (15.5mm), whereas our discs are actually just a bit smaller (~14.5mm).
