3-Piece Kelso Set

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

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!

Love the Zak cups. Now that my toddler is 2.5 I wish they were larger so we didn’t have to fill it up while out and about for several hours, but they’re a great size for younger than her because that’s only a recent problem. The design comes off slowly in the dishwasher, I’m not too worried about this but some may care about that. The stainless steel are my favorite, I prefer them over the plastic just since it’s healthier but I still have a couple plastic ones. My daughter loves blue and baby shark so they were the perfect for her. We take these with us everyone on the go and they almost never leak. We only own Zak cups and have used them since 6 months old.

Great for toddlers keeps beverages cold and easy to grip for small hands. Does not leak and great quality. I have purchased several of these brands

We have had these cups for 3 weeks. 4.5 stars for leaking. The plastic cup has leaked about once a week. Not bad leaking compared to other cups we have used. But this does still leak occasionally when the liquid warms and pressure builds. The stainless steel has only leaked once, and that was when I found it lying on its side. 5 stars for sturdiness. These have been dropped and thrown multiple times. No dents or cracks. 3 stars for decal. The decal on the plastic cup began scratching off almost immediately. The decal on the stainless steel is still intact. It has not scratched off at all. 3 stars for the straw. The straw is cut at an angle at the bottom and is about a 1/4" from the bottom of the cup.

I loved our sons Contigo cup but after the lids shrunk from sterilizing them and then they started leaking, I decided to try these after they were recommended to me. I didn’t want to commit to 2 cups so my friend told me about this set where you get one plastic and one stainless steel. Haven’t used the stainless steel cup yet since my son is very much in the throwing phase but the plastic cup does the job. It’s very easy to use but I can imagine if it was the first straw cup your child was using that it could be a little difficult to drink out of. My son has thrown it multiple times off his high chair and minor scratches or nicks but I have noticed that sometimes after throwing it that the inside straw will disassemble from the outer straw. Easy fix though to just readjust it. It’s not fully leak proof although it was more so in the beginning than now. My son is in this phase where he will put the bottle upside down and smush the straw to the tray/table and water will leak out. He also throws it off the high chair even when attached to a bungee cord but when it’s upside down will also drip out. I do agree with other reviews where the design does wear off. We’ve been using this cup for a month and the design is already wearing off so be careful which design you choose since it might be more noticeable on certain ones. I still think it’s a good cup, easy to clean, and a good value for 2 cups especially one being stainless steel.

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!

Fantastic product ! Leak free ! Perfect design for any Mickey lover withstands the dishwasher!

Le gustó mucho a mi niña, está de muy buen tamaño y de muy buena calidad , para llevar a todos lados !

Kids love them great quality

These cups are great for toddlers especially ones that like to tip cups over. Hardly any spillage!

Súper lindo y resistente mi hijo los amantes

Easy to wash, most importantly it doesn’t has hard to reach areas unlike my previous cup where mould’s started to grow. Like that the straw is safe from child’s chewing as well.
