The Humangear GoToob+ 3-Pack 100ml Bottles  are soft silicone bottles free from BPA, PC and Phtalates. It's easy to squeeze the contents and the wide opening makes it easy to empty and clean. GoToob + takes care of previous versions' user-friendliness, but in new skimmer and with more  reliability. The bottle is designed with LoopLock, which is practical both to prevent leakage and to hang up the bottle in the shower. A textured surface on the collar allows you to type what it contains with a waterproof pen so that you easily separate your bottles into the gasket. The bottles are approved for food so they are also great for bringing sauces and other condiments on the walk or weekend.  Humangear GoToob+ 3-Pack 100ml Bottles Features Soft and durable silicone LoopLock - prevents the lid from opening and can be used to hang Large opening, easy to fill and clean Can stand on your own Large, clear markings for volume Textured surface on collar for marking content with tag pen Size approved for security checks at airports Do not use the bottle to store alcohol or fuel for your open air cooker Material approved for food, free from BPA and Phthalates
