These reusable, trademark tubes are perfect for creating and transporting travel size quantities (roughly 60g) of personal care products, beverages, and condiments. They are compliant with all the international carry-on rules, and all you need to do is simply fill them and go wherever you need. Each tube is leak-proof and spill-proof, and they're made from eco-friendly, food-grade silicone that is BPA free. Another clever part of this package? Little stickers are provided that you can use to easily identify the contents of each tube.
