This wax is designed especially for use in hot glue guns. This is the easiest wax to use if you need to make a lot of seals. This wax is Faux wax that is the same as our standard wax and has additives added to the mixture to make it stronger and flexible. This type of wax is recommended for invitations that have to travel through the postal system due to its high strength and flexibility. This sealing wax is easy to use and does not require you to lubricate the seal when using. Our Glue Gun sealing wax sticks are available in many different colours and are 10mm in diameter. Each 10mm stick will make around 8 to 10 seals at 25mm diameter. We also recommend a temperature controlled glue gun set on low. High-temperature glue guns will need to be manually switched off when they reach the correct melting point of the wax and turned back on when the temperature drops.
