GelGems® bag (small: monster mash)

I put these on my sliding glass door and they peel off so cleanly—no sticky residue at all. The monster shapes are fun and the gel holds up well even after a few days of sunlight.

I was skeptical about window clings making a mess, but these rinsing clean with zero residue is a game changer. The monster shapes are delightfully weird and my kids have rearranged them on the sliding door about ten times already without losing stickiness.

These clings stick really well to the glass but peel off in one piece with zero sticky mess, exactly like it says. I stuck a few on my sliding door and the goofy monster shapes make me smile every time I pass by.
