Cobbler’s Wax. Complete with a piece of leather to use as a hand grip. This cobblers wax is specially formulated to apply black wax to the first bit of hemp for extra sticking power. It is used when starting to hemp a joint on the set of pipes, and helps to prevent the hemp from spinning. This wax is also formulated so that it will not melt in your pipe case as has been the custom in the past with some waxes.
