Sticker Workshop

The sticker workshop is a 2 unit room where stickers are upgraded using glitter or merged together. You can also convert shards and stickers into glitter. The sticker workshop only has 1 upgrade level and is unlocked in situation room level 8. Leveling up stickers requires glitter and cash to complete.

The in-game description says: This room allows you to enhance or merge stickers, attach them to items, or recycle shards into glitter.
