Sealing wax sticks are made of flexible sealing wax and molded to fit into a Full-Size (also known as Regular Size, NOT Mini) glue gun. You don't need to use flame, there will be no soot in your finished wax seals, and using glue gun wax can be faster than using traditional sealing wax with a wick! Each stick is approximately 5.3 inches long x 0.43 inch diameter Suitable for craft projects, wedding and party invitations, letter-sealing, bottle-sealing, signature, etc.
