## Description

This leak-proof tumbler set from Zak Designs makes hydration fun for any Mickey Mouse fan! Durable Materials: The set includes two different tumblers, one made from plastic and one made with double-wall stainless steel; both are durable enough to use every day. The comfortable straws are made from silicone, and everything is completely BPA free. Leak-Proof Straw: The straw has a built-in valve that allows liquid to flow when drinking and prevents spills when the tumbler is tipped over. It's perfect for travel or for young children graduating from sippy cups. Hydrate Anywhere: Choose lightweight plastic or double-wall stainless steel, whichever suits the situation! The tumblers won't splash or leak, making them ideal to take on the go. At home, you don't have to worry about spills around papers or electronics, and drinks stay easily accessible through the straw. Specifications: 1 plastic tumbler (15 oz), 1 stainless steel tumbler (12 oz), 1 additional sipper and straw. Made of durable plastic, stainless steel, and silicone. BPA-Free - Zak is committed to safety. Lids and plastic tumbler are top rack dishwasher safe, hand wash stainless steel tumbler; do not microwave. Character: Disney's Mickey Mouse.

Review: Perfect Tumbler Set for Dino-Loving Kids - I bought the Zak Designs Dino Camo Kelso Tumbler 3pc Set for my two grandkids, and they love it! The fun dino design is a hit, and I love how practical it is—leak-proof lids, durable plastic and stainless steel, and the straws are perfect for little ones. Easy to clean and great for travel or home. A great combo of fun and functionality. Highly recommend for kids on the go
Review: My FAVORITE sippy cup for transitioning my toddler! - I was in the market for some toddler cups since my little one needs to transition away from bottles. I bought a couple different types but these Zak cups are BY FAR my favorite! They were highly recommended by a lot of parents and specialists on TikTok. The price is fair for the quality of the materials. I got the set with a steel tumbler and a plastic cup so I could compare (and avoid plastic when possible). They are both high quality, super easy to wash, are dishwasher safe, and the designs are exactly as pictured. My daughter does really well with these, and the straw top is a soft silicone so she gets to teethe on it too. I usually don't add the plastic straw because my kiddo likes to tip the cup back like it's a bottle. These cups are pretty leak-proof! She can spill an occasional drop or two here and there but it's no different than how much she would spill with her bottle. The only thing that I can call a con is the fact that these don't have handles, which I think would make it easier for my kiddo to hold, but she manages fine without them for the most part. Also, the steel tumblers are heavy and could do some damage if dropped on a foot or flung into a wall (she's in a throwing stage) so we only use them with close supervision. If you are looking for a cup to transition your baby away from bottles, I would definitely recommend these! So far, these are my daughters (and my) favorite cup. I have already bought 2 more sets. Hope this helps!
