The Kelso tumbler has a valve in the spout, which lets water flow freely when kids are drinking, but stops spills if the tumbler is tipped over. **Q: Is the tumbler easy to clean?** A: Yes, both the spout on top of the lid and the inner straw underneath the lid are removable to make cleaning easy, and the parts are all dishwasher safe. **Q: How old should my child be to use the Kelso tumbler?** A: We recommend this tumbler for kids age 3 and up. **Q: What kind of drinks can go in the Kelso tumbler?** A: The Kelso tumbler is perfect for everyday cold beverages like water, milk, or juice. Thick smoothies are a little more difficult to drink with the valve, while carbonated drinks can build pressure and push liquid up through the straw. **Q: Can I travel with the Kelso?** A: The Kelso tumbler fits in most car and stroller cup holders for on the go convenience. We don't recommend putting the Kelso tumbler in a bag, as pressing on the soft spout can open the valve and allow drinks to flow out. ## Frequently Bought Together - Zak Designs 15oz Baby Shark Kelso Tumbler Set, BPA-Free Leak-Proof Screw-On Lid with Straw Made of Durable Plastic and Silicone, Perfect Bundle for Kids (2pcs Set) - Zak Designs Kelso Toddler Cups For Travel or At Home, 15oz 2-Pack Durable Plastic Sippy Cups With Leak-Proof Design is Perfect For Kids (DinoRoar, Zaksaurus) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/394796695-zak-designs-15oz-baby-shark-kelso-tumbler-set-bpa-free](https://www.desertcart.vn/products/394796695-zak-designs-15oz-baby-shark-kelso-tumbler-set-bpa-free) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-22*
