Made from soft, rugged, silicone that’s easy to squeeze so you can get every last drop out, this tube is TSA approved and perfect for all your travels. Featuring a large opening, this tube is easy to clean and fill. The contoured base allows the GoToob to stand up for faster filling and the textured area on the collar is the perfect spot to do your labeling without any ink rubbing off. Say goodbye to leaks with the LoopLock which makes it almost impossible to accidentally open the cap! The loop can also be used to hang the tube from a hook or clip it to the outside of your pack for easy storage when traveling.
