Glue gun sealing wax is the modern-day version of traditional sealing wax. Completely flexible and mailable, the wax can easily be melted and dripped. Although not the traditional sealing wax, our glue gun wax is made from genuine wax, not colored glue like some. Fits any standard size glue gun. Full instructions included. Kit has enough sealing wax to seal 100-125 invitations. Comes in your choice of Gold, Silver or Pearl wax, and brass seal with a swirled heart design.
