Crayola - School glue is essential for everything from science projects to history presentations, and world-class works of art. It’s even essential for slime supplies! But not all kids’ glues are washable, clear, or nontoxic like Crayola Washable No-Run School Glue. Since our glue doesn't crack and chip away, kids can hold onto their creations for much longer. Plus, the convenient size of our 4 oz glue bottle is perfect for backpacks, while the special applicator tip prevents clogging, so it's always ready for use.
