This acid-free, non-toxic, glue is strong and fast bonding. The Mega Glue Stick contains 1.41 oz. of glue that works well for paper-based school, home and office projects. It appears purple when applied as a guide for precise adhesion, but dries clear and unnoticeable. It cleans off hands and household surfaces with soap and water, and features a choke-resistant cap designed for safety. Brand: 3M
