Alcolin Sticky Putty is a pliable, moldable putty that provides an alternative to adhesive tapes, tacks, and other mounting materials. Use it to hang posters, calendars, artwork, and more without damaging walls. Sticky Putty comes in an easy-access sleeve that keeps the product clean and dust-free until you're ready to use it. It will not dry out and remains sticky and re-useable for an extended period of time. A single blob the size of a quarter will hold 10 oz on a wall.
