GelGems® bag (small: crayons)

We put these on our sliding glass door and my toddler spends ages rearranging them. The crayon shapes are a fun twist for a kids' room window.

Peeled one off the sheet to test it and was surprised how easily it stuck to our sliding glass door without leaving any residue. The colors really pop against the light, making the room feel cheerful. Only wish the bag came with a few more pieces for the price.

My toddler spent a whole quiet hour sticking these to the sliding glass door, and they actually peel off clean without any sticky residue. The crayon shapes are bright enough to see from the street but let light through nicely.
