text: The LEXO uses bio-based phase-change and advanced heat transfer materials to absorb the initial heat of the beverage and cool it to a more drinkable temperature. When the temperature begins to drop, the LEXO slowly releases the stored heat back into the drink. The LEXO can also insulate cold liquids.
  The LEXO has three layers of 18/8 stainless-steel and BPA-free plastic lids.
