This is a 2 piece frame that can be used to hang or place your waifu stickers. I wasn't sure I wanted them anywhere permanently so being able to stick the frame anywhere is a good solution in the meantime. You don't have to peel the backing off to place them in the frame but it can make for some cool designs with glow-in-the-dark filament.
It uses 4, 6x2 mm magnets in the back. The same is used for gridfinity bins.
