Baseplate wax. Perfect for plugging the ends of your tubes to avoid getting glue inside. Simply push the tube end into the wax like a cookie cutter for a seal and push out when you're done. The number of tubes the wax will plug depends on the tube size. Getting glue inside the tubes is the number one cause of pen kit failure.
Sold in a set of three sheets, as pictured. Tube not included.
Price per pack in Canadian dollars.
