Sticks are molded to fit into a Full-Size (also known as regular size) glue gun. You don't use a flame, there will be no soot in your finished wax seals, and using glue gun wax can be up to 10x faster than using traditional sealing wax with a wick! Each stick is approximately 3 3/4" long by 7/16" diameter, and will make 10-15 wax seals when using a 3/4" diameter wax seal stamp. (The number of wax seals you get per stick may vary, depending on your technique and the size of your seal stamp.) This wax may not adhere well to glossy paper. **We highly recommend using a Low-Temperature full-size glue gun (or a dual-temperature full-size glue gun set to Low Temperature). The wax will be slightly thicker when dispensed from a low-temperature glue gun, making it easier to control when making wax seals. Sticks can also be melted in a melting pot and the melted wax poured onto your project using a Wax Melting Spoon.**
