Review: Good cup for toddlers - The cups themselves do a good job of not leaking for the most part but if they get dropped a lot the lid doesn’t quite line up properly so it will slightly leak. The cup also comes apart to make it easier to clean, you will need a little cleaning brush to clean the silicone straw that has a few spots that I’ve noticed start to grow mold but it’s easy to clean when a small straw cleaner brush. The cup is a great size for my toddler to hold and the cup itself hold a good amount of water. The paint/design does not hold up very well, I’ve hand washed as well as used the dishwasher and both cause the design to start coming off. ## Features - SIZE: The set contains two Bluey tumblers that are 3.16 inches in diameter and 6.67 inches tall. They have a capacity of 15 ounces. - MATERIAL: The durable tumblers are made of plastic with silicone straws. They're dishwasher safe and should not be microwaved. - LEAK-PROOF DESIGN: The silicone straw has a built-in valve that allows liquid to flow when drinking and prevents accidental spills when the tumbler is tipped over. The straw is also soft and comfortable for kids to drink from. - AT HOME OR ON THE GO: The straw tumbler is suited for travel, since it won't leak and fits in car cup holders while keeping drinks easily accessible. It's also great for drinking beverages at home without worrying about stains or nearby electronics. - LIFESTYLE: Zak Designs drinkware makes hydration fun! These Bluey tumblers are a great gift for any fan or kids just graduating from sippy cups. The tumblers are fully reusable--no more disposable cups--and a fun addition to the daily routine. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08XWQFRCH | | Age Range Description | Kids 3+ | | Best Sellers Rank | #46 in Baby ( See Top 100 in Baby ) #2 in Toddler Cups | | Brand Name | Zak Designs | | Capacity | 15 Fluid Ounces | | Color | Bluey | | Customer Package Type | Standard Packaging | | Customer Reviews | 4.6 4.6 out of 5 stars (30,579) | | Finish Types | Glossy | | Global Trade Identification Number | 00707849125092 | | Included Components | Lightweight Tumbler, Straw Lid | | Is the item dishwasher safe? | Yes | | Item Dimensions W x H | 3.2"W x 6.67"H | | Item Type Name | Todder Cups | | Item Weight | 5.6 ounces | | Manufacturer | Zak Designs | | Manufacturer Part Number | BLUA-U265 | | Material Features | Lightweight | | Material Type | Plastic | | Material Type Free | Lead Free | | Model Number | BLUA-U265 | | Number of Items | 1 | | Occasion | All Occasions, Birthday, Christmas | | Other Special Features of the Product | Dishwasher Safe, Leak Proof, Lightweight, Soft Straw | | Pattern | Solid | | Product Care Instructions | Dishwasher Safe, Hand Wash Only | | Product Style | Drinkware | | Recommended Uses For Product | Home, Travel | | Reusability | Reusable | | Shape | Round | | Size | 15 Ounces | | Specific Uses For Product | Cold Drinks | | Subject Character | Bluey | | Theme | Adventure, Animals, Cartoon | | UPC | 707849125092 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Zak Designs - **Capacity:** 15 Fluid Ounces - **Color:** Bluey - **Material:** Plastic - **Special Feature:** Dishwasher Safe, Leak Proof, Lightweight, Soft Straw ## Images ![Zak Designs 15oz Bluey Kelso Tumbler Set, Leak-Proof Screw-On Lid with Straw Made of Durable Plastic and Silicone, Perfect Bundle for Kids, 2 Count (Pack of 1) - Image 1](https://m.media-amazon.com/images/I/71TKQXgMx9L.jpg) ## Available Options This product comes in different **Color, Size, Style** options. ## Questions & Answers **Q: Does the Kelso prevent spills when the tumbler is tipped over?** A: Yes, and you don't need to remember to close the lid! 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ the only toddler cup I recommend *by A***R on April 1, 2026* absolutely love these cups for my toddler. spill proof, cute & easy to clean. they’re durable & good quality, they’ve quickly become to only cups we like to give our 2 year old. ### ⭐⭐⭐⭐⭐ Good cup for toddlers *by A***K on December 15, 2025* The cups themselves do a good job of not leaking for the most part but if they get dropped a lot the lid doesn’t quite line up properly so it will slightly leak.

The colors are bright and fun, and the SuperKitties designs are adorable — my little one was instantly obsessed. The size is perfect (15 oz), and I love that they come in a 2-pack so we always have a clean one ready to go. The best part? They really are leak-proof. I’ve tossed them in a diaper bag and they haven’t spilled once. The straw is soft and easy for toddlers to drink from, and the cups feel sturdy and durable — not flimsy at all. They’re great for home, car rides, and on-the-go. Easy to clean and hold up well after multiple washes. Definitely worth it and I would 100% buy them again! ## Frequently Bought Together - Zak Designs 15oz Bluey Kelso Tumbler Set, BPA-Free Leak-Proof Screw-On Lid with Straw Made of Durable Plastic and Silicone, Perfect Bundle for Kids, 2 Count (Pack of 1) - 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) - Infantino My 1st Tumbler – Adorable Miniature Tumbler with Leak-Resistant Straw and Toddler-Friendly Handle, Encourages Hydration, Easy to Clean, 9 fl. oz, Ocean --- ## 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.kr/products/329407052-zak-designs-15oz-bluey-kelso-tumbler-set-leak-proof-screw](https://www.desertcart.kr/products/329407052-zak-designs-15oz-bluey-kelso-tumbler-set-leak-proof-screw) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-05-12*
