The thermoTANKA 350ml bottle is designed for kiddies, or for adults who want a bottle that will fit into a small bag or handbag. It holds a volume of 350ml (one large glass) and ideal for keeping your milk cold well on the go, measuring approximately 152mm from the bottom to the top of the stainless steel area.  The vacuum properties of the thermoTANKA can keep your drink hot for 6+ hours and cold for 12+ hours.  
thermoTANKA fits all of the standard ECOtanka lids (except the megaTANKA lids).
 
Care Instructions:
ECOtanka bottles are very easy to care for: simply wash and rinse well the same as for your dishes.   Alternatively, baking soda and warm water can be used to cleanse and freshen your bottle.  They may be sterilized with boiling water.  Do not place in the freezer.
We do not recommend washing any stainless steel bottle in your dishwasher.
