Confidently apply adhesive to every spot that needs it with disappearing purple color Glue Stics. Simply lift the cap and twist the base for easy application. Apply the right amount of adhesive with an easy-to-see purple glue that disappears once dry. Glue goes on smoothly; permanent adhesive bonds securely to a variety of materials but washes easily off hands and clothing. The fast-drying glue applies smoothly and neatly to paper cardboard fabric and photos making it ideal for arts and crafts. With this Glue Stic you can apply glue without leaving a visible trace. All Avery Glue Stics are nontoxic photo-safe ACMI certified and conform to ASTM D 4236.
