This 750ml Tritan bottle, in lilac/green, from iDrink, reference ID2121, 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. Unlike the lilac/orange color, which is only available in 500ml, 1000ml, and 1500ml sizes, the lilac/green pattern is also available in this intermediate 750ml capacity. It is a preferred option for those seeking this color contrast in an intermediate volume between 500ml and 1000ml.
