Scotch Restickable Tabs are pre-cut squares with clear, reusable and removable adhesive for lightweight mounting. Hang photos, posters, artwork or other lightweight objects on walls, refrigerators, windows, and most other flat surfaces. Reuse again and again. Each clear tab with double-sided adhesive removes cleanly from objects and surfaces and can be used instead of magnets, tacks and putties. Photo-safe adhesive will not stain walls. Use on most flat surfaces, including stainless steel, plastic, concrete, glass, wood, painted walls and more. Each tab holds approximately 1/2 lb.
