The dots are made by layering the duct tape to sheets of wax paper and then punching them out with a gasket punch. You could, of course, also just cut them out if you don’t have a gasket punch sitting around. The wax paper is layered in a way that creates an easy to remove backing so you can store them anywhere. After all, you never know when you’re going to need a little duct tape to patch up a hole or fix something.
