With so many hot melt glues and so many surfaces to bond, how do you know which glue is the right formula for the job? Well, sometimes there is more than one option that will work for you. The best way to know for sure is to test one or two glues. An economical way to decide which glue is right for your project is to purchase a 1 lb. sample pack. Most of our glue formulas offer a sample pack is 18 sticks in the 7/16" x 10" sticks.
