The Crescent Bottle features a non-slip, rubbery band around base to keep it from sliding on smooth surfaces. The screw-on lid won't leak when it's closed, and is attached to the bottle with a carrying loop--you can hold it on your fingers or clip on to bags and backpacks. The bottle has a capacity of 24 ounces, about 3-1/4 inches in diameter and 7-1/2 inches tall. The durable plastic bottle is dishwasher safe and BPA free, but not microwave safe. Recommended for children ages 13 and up.
