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 dont 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! This wax is hand-poured in the U.S.A. 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.) **We recommend using a Low-Temperature full-size glue gun, or a dual-temperature full-size glue gun set to Low Temperature. Sticks can also be melted in a melting pot and the melted wax poured onto your project using a Wax Melting Spoon.** Made in the U.S.A.!
