LotFancy 60 clear empty lip balm tubes with snap-on caps; Each tube is 5.5ml (3/16 oz), the perfect size for lip balm and lipstick; Compact size makes it an easy fit for pockets, purses and pouches. These lip balm container tubes are made of food-grade plastic, odor-free, BPA free and non-toxic; material ensures no warping when pouring hot mixes into the tubes; No material deformation or cracks during the cooling process. These lip balm containers come with a roll-up mechanism to effortlessly push your lip balm to the top for quick and easy application. NOTE:Max recommended filling temperature is approx 120F (49C). Filling with a solution that is too hot can warp the plastic ; damage the mechanisms. Containers are not "watertight", so pouring too hot can also cause leaking (until the formulation solidifies). If the solution placed in them is too thick or pasty, the twist mechanism cannot freely move the product up and down. Do not microwave, boil, dishwash or fill with extremely hot or corrosive contents. Make sure to screw the tube down to the base before pouring; Let your liquid cool a little before pouring into the tube.
