The water bottle holds 16 ounces and is made of durable plastic, which is BPA-free and sturdy enough for kids to take anywhere they want. When it’s not being used, just cover the comfortable silicone spout to keep it clean; it opens easily (even for kids!) at the push of a button and has a flip-up lock to keep it shut. The lid screws on securely, won't leak when the spout is fully closed, and has a built-in carrying loop for traveling convenience, making this lightweight drinking bottle perfect for everyday adventures. Don't put it in the microwave—it's made for cold drinks—and the bottle is dishwasher safe, though we recommend hand washing to keep the artwork bold and bright.
