MADE IN THE USA - Our 50 cavity filling tray makes it easy to fill lip balm tubes quickly and efficiently. Just insert the top of the tube into the bottom of the tray (50 times), pour your base on the top and scrape off the excess. It takes about 2 hours for the balms to cool and they are ready for removal. This tray works with our standard lip balm tubes. We can not guarantee they will work with other suppliers tubes.
