These lovely little animal index labels stand out in a way that will make you smile every time you look for a page. Each set comes with 24 black and white index stickers and 24 numbers (two sets of numbers 1-12). The numbers can be affixed to the index stickers. The index stickers measure about 0.8 inches wide from head to tail and are about 0.5 inches high. They have fairly strong adhesive, so though you can peel them off you probably don't want to attach them to fragile book paper unless you want them to be permanent. Ideal for office use, scrapbooking, organizing school notes and more!
