Make hydration easy and fun for Barbie fans with a reusable water bottle by Zak Designs! Vacuum Insulation: The drinking bottle has vacuum insulation that keeps drinks cold for up to 20 hours, so your water is always refreshingly chilled. The double-wall construction also prevents condensation from forming on the outer walls, eliminating messy water rings. Reusable and Durable Material: Reusable water bottles will last wash after wash-good news for you and the environment! The 19 oz water bottle is made with food-grade, 18/8 stainless steel, durable enough to use every day and bring on any trip. Leak-Proof Lid: The lid screws on securely and won't leak when the spout is closed, though water flows for easy drinking when the spout is open. The easy-open button has a flip-up lock to keep it from activating accidentally. On the Go: The water bottle has a built-in carrying loop on the lid for easy transportation, and with the spout cover to keep the spout clean and closed, it can be tossed into a bag for worry-free travel. Specifications: 19 oz capacity. Vacuum insulated, stays cold up to 20 hours. Made of durable stainless steel. BPA-Free - Zak is committed to safety. Hand washing recommended, do not microwave.
