These Wall stickers when used alone, can be re-used and repositioned without leaving a sticky residue.
Simply peel carefully from sheet. Then position it in the desired location making sure that the surface/wall is clean and dry (newly painted walls should be left at least 3 weeks to completely dry) and smooth onto surface making sure to remove all bubbles.
To remove or reposition, slowly peel off the wall and re-apply in the new position.
