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!

### ⭐⭐⭐⭐⭐ Best toddler cups
*by D***E on January 23, 2026*

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.
