Elmer's Tac'N Stik is a removable adhesive putty that replaces tapes and tacks. It is ideal for hanging light weight items such as posters, maps, and paper decorations. This putty works well on non-porous surfaces such as walls, doors, and refrigerators. Tac'N Stik is easy to use, stays moist, and won't mar most surfaces. It is non-toxic and can be easily removed and reused again and again.
