This water bottle holds 473 ml and is made of durable, BPA-free plastic. The screw-on lid has a built-in carrying loop for easy transportation, and doesn’t leak when it’s closed, so the bottle can be tossed into a bag for worry-free travel. When it’s not being used, the comfortable silicone spout can be covered to keep it clean. The bottle is dishwasher safe and should not be microwaved. Recommended for children ages 3 and up.
