This 500ml Tritan bottle, Axolutely themed, from iDrink, reference ID2121K, is a reusable bottle made of transparent copolyester. Tritan is a BPA-free, transparent, and virtually unbreakable copolyester that does not retain odors or stains and is resistant to both heat and cold, and is dishwasher safe. The Axolutely theme is inspired by the axolotl, a uniquely shaped amphibian that has become popular as an exotic pet and internet sensation. It is a preferred option for fans of this less conventional animal than the more classic themes in this range.
