The Zak Designs 18oz Barbie Kids Straw Handle Tumbler is the ideal choice for active kids. This durable stainless steel tumbler features a vacuum insulation design that keeps drinks cold while preventing condensation from forming, so there are no annoying water rings to clean up. The silicone straw includes a built-in leak-proof valve that stops liquid flow when the tumbler is not being used, making it easy for children to stay hydrated without creating a mess, even if the tumbler tips over.

With an antimicrobial drinking spout, this tumbler helps limit the spread of bacteria, allowing parents to feel at ease when taking it on the go. This 18-ounce tumbler is both reusable and BPA-free, promoting a healthier lifestyle. For cleaning, we suggest hand washing to maintain the vacuum seal and keep the vibrant Barbie artwork intact, while the lid is dishwasher-safe on the top rack for convenient cleaning. This tumbler combines practicality with style, making it a fantastic option for kids who are always on the move.
