A really good storage system for your liquids. Shampoo, soap, ketchup or mustard - everything is kept safely, leak proofed and easily portioned. The tubes have folding lids and disperse the contents when compressed. Dripping is prevented by a silicone lip at the hole. The lids are removable for easy cleaning and filling. Turning the lids displays gradations for the liquid levels. The tubes are made of silicone and are extremely flexible and robust. Equally, they are perfect for the current flight regulations. Super additional detail: the 60 ml models are fitted with a `sucker´ enabling your `GoToob´ to be fixed to a bathroom mirror thus keeping your hands free. Not suitable for fatty products.
