The KingCamp Water Bottle is very sturdy and at 17.7 ounces can hold a lot of water. It is made of TRITAN and is BPA free. The water bottle is marked with both mililiters and ounces. The top opens with a click of the button and is leak proof. The bottle top screws off and is large enough to add ice cubes and to clean. The water bottle is 8.7" tall. #RankBoosterReview ii, Sponsored iii, KingCamp Water Bottle https://www.amazon.com/gp/product/B017B4L4ZM/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1
