GelWonder™ bag (small: ninjas)

Bought these for my son's bedroom window and he's been creating new battle scenes every day. The gel material holds up well on the glass and doesn't leave any sticky residue when peeled off.

My daughter has been rearranging her ninja army across our sliding glass door every morning. The gel material holds firmly but peels off without any sticky residue. It's a clever way to keep her entertained without a single mess to clean up.

These ninjas stick to our bathroom mirror like they’re glued, yet peel off clean in one piece every time. The gel is thick enough that my kid can’t bend them into a permanent knot, which is a win.
