Since 1923, Best-Test Paper Cement has been made in only one way – with a specially-blended and treated formula that uses premium white rubber imported from the Far-East. Best-Test Paper Cement is the overwhelming choice of commercial and fine artists, crafters and teachers. Unlike multi-purpose glues, Best-Test Paper Cement will not shrink or wrinkle the paper when adhering. It's a true adhesive. Dries quickly and clear. Easy to apply and easy to clean up! Ideal for mounting, paper crafts, leatherwork, scrapbooking and more. Acid-free.
