This is a fairly simple paper towel holder that is designed with holes in the bottom of it to glue up to 5 magnets ¼" in diameter by ¼" long to the bottom to hold the dispenser to any metal surface such as a tool box. The link below is to the magnets that can be used. Glue as many or few as you want into the base.
