Clear and discreet, Scotch mounting squares do not harm objects, are photo safe, leave no oily residue and are easy to apply and remove. The double stick adhesive is perfect for projects that require a temporary hold such as posters, banners and for attaching objects to foamboard. They hold objects weighing up to one pound. Mounting squares measure 11/16" and are available in packs of 35. Use in place of adhesive mounting putties that stain and damage walls.
