This 750ml Tritan bottle, featuring a bee design, from iDrink (reference ID2120I), 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, making it dishwasher safe. This is the larger capacity version of the same bee design, also available in 500ml. It's a great option for those who like this design but need more volume than the 500ml version.
