Silicone Lip Balm Pouring Tray: Finally, we have a product that will solve your lip balm pouring problems! This pouring tray will allow you to quickly and effortlessly pour 48 lip balms at one time. We have been making lip balm for over 12 years and have found that the Silicone Filling Tray is much better to work with than the ridged plastic ones. With our trays it is easy to attach the tubes, easy to detach the tubes, and easy to clean up when done. There are no sunken in tops on the tubes, it leaves a nice flat surface. Scrape off any overpour, remelt and make another batch. Fits standard .15 oz Round Lip Balm Tubes. Comes with instructions on how to use this tray to make lip balm. The lip balm filling tray is a great tool used to fill multiple .15 oz (standard size) lip balm tubes. The neck diameter of a standard tube is approximately 0.55 inches. The lip balm filling trays allow you to neatly fill up to 48 lip balm tubes at once, ultimately speeding up the entire lip balm production process. Note: Not all tubes fit the ridged plastic trays, ALL tubes will fit this tray because it is flexible silicone. Let me know if you have any questions.
