All aboard for a versatile way to design a child's room! It's a piece of cake really. You give them the stickers, let them put them wherever they want, then let them change places should they so desire. Other stickers, naturally, would be ruined if you tried to remove them, not to mention what would happen to the wall or furniture to which they were stuck. These stickers can be used for years without loss of their adhesive qualities and without concern for damage to most surfaces.
These stickers will work on just about any surface, but take care with wallpaper or some delicate surfaces. If in doubt, test in an inconspicuous place prior to applying all the stickers. Also, wait 10 to 15 days after painting before using stickers. Though the paint feels dry, it needs adequate time to cure. As with any adhesive product, these will work much better on clean surfaces free of dust and the like. Specifically, they will work well on surfaces including but not limited to walls, mirrors, your fridge, laptop covers, tile, glass, lockers, furniture, and automotive surfaces.
