The Zak Designs water bottle holds 20 ounces and is made of food-grade stainless steel durable enough for kids to take anywhere they want. It s vacuum insulated so cold drinks will stay that way for longer and you ll avoid leaving messy water rings since condensation won t form on the outside. It opens easily (even for kids!) at the push of a button and has a sliding lock to keep it shut. The lid screws on securely won t leak when the spout is fully closed and has a carry handle for traveling convenience making this bottle perfect for everyday adventures. It even comes with a silicone bumper to protect from dents and scratches! Don t put it in the microwave—it s made for cold drinks—and the bottle should be washed by hand to preserve the vacuum seal and keep the artwork bold and bright.
