Zak Designs CoComelon Kelso Tumbler Set, Leak-Proof Screw-On Lid with Straw, Bundle for Kids Includes Plastic and Stainless Steel Cups with Bonus Sipper (3pc Set, Non-BPA), 15 fluid ounces

My son absolutely loves these cups! We mainly use them for milk, and they’ve been completely leak-proof—no drips at all. He’s super active and has dropped (and even thrown!) these cups multiple times, and they still work perfectly. They’re incredibly durable and easy to clean. The Blippi design is a huge bonus—my son gets so excited every time he uses them. Highly recommend for any parent looking for a reliable, toddler-proof cup with a fun design!

These are great for toddlers. They do not leak if tippoed over. If star liquid is cold, it will push up and leak very slightly from the straw top. I’ve found all cups do this so it’s not a deal breaker. I love that this comes with an insulated and non insulated option. The colors are vibrant and they have held up well with a wild toddler. I love that it comes with extra spout and straw.

Absolutely love these cups! Doesn’t leak, easy to wash! My daughter loves the unicorn print!

These are adorable and super durable. No leaks, easy for little hands, and dishwasher safe. Win-win!

Good cups but leakWill probably have to use only for water for now until baby stops putting things upside down

I love these. Bought them for my grandboys (2 and 4) for when they visit. Great quality, the kids love them and spill proof!! Well worth the money especially since you get an extra straw and top. Buy them!

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!

Spill proof. One plastic cup and one stainless steel cup. Cute design.
