AdTech’s Removable Tape Glue Runner Refill is a replacement cassette for the complete unit, and is both acid-free and safe to use on photos. The adhesive bonds instantly to paper, ribbon, foam, plastic, wood and many other materials, making it ideal for scrapbooking, photo albums and a host of crafting projects. The standout feature of this glue runner, however, is that the adhesive is repositionable, allowing the user to fix mistakes, change locations, or remove materials cleanly.Details:8.75 yd. each2 refillsRemovableAcid-freeNontoxicPhoto-safe
