It’s a sticker that becomes a little wall pocket. Stickr Pockets– no hammers, no nails, no “e” in Stickr, no hooks, no hassles, no putting anything too heavy in them. Seems like a worthy alternative to a shelf if you just want to stash a few lightweight items on the walls. Made of vinyl by Butch and Harold, they peel on and off the walls easily without damaging the surface.
