Zak Designs Shells 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)

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!

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.

Had these for months now. They’ve held up from hand washing, top rack dishwasher cycles and being tossed around by a toddler. Only had a leak once but that was my fault for forgetting to put the seal ring in the lid. Also, my toddlers favorite cups.

This cup comes with both stainless and plastic options, and I purchased it to transition my baby from a sippy cup to a straw. While my baby is comfortable using straw cups for water, he refused to do so with milk, and the doctor recommended it to regulate milk intake. I've tried various types, but cleaning and drying the straw proved challenging. I chose this cup based on reviews mentioning its leakproof design. Given that my baby tends to throw things, I started with the plastic version. Once he gets accustomed to it, I plan to switch to the stainless steel cup. I bought this cup a month ago, and just recently, my baby started drinking milk from it accidentally during an outing when I didn't have the sippy cup. After initially refusing for about an hour, he eventually accepted it. I appreciate the cup's quality construction and the flexibility it offers with two material choices. The cute design appeals to my baby, and the straw is robust enough for teething, leaving no marks even when bitten. Overall, a well-made and versatile cup that caters to different situations.

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.

These are wonderful. Spill proof, great size, dishwasher safe.

My two year old loves her cups I got these in June and now have several she won’t drink out of anything else easy to clean and easy to assemble no big messes since switching to these cups

We have used the Contigo straw cups for years, and while they are sturdy and leak proof, the straws were so hard that I always worried about my kids impaling themselves on them (not to mention the potential interference with speech development). Well, recently, one of our Contigo straw cups broke, and while I was looking for a replacement, I came across these. And, well, I haven’t purchased a lot of Zak products because even though they are quite cute, the only water bottle I had purchased from them was quite flimsy and leaky. These had really great reviews, a flexible straw, and all the characters my kids love, so I went ahead and ordered them. And I am glad that I did! They were packaged in cute boxes and the set came with an extra straw part. The straws are flexible and the cups survived my leak test without dripping at all. What’s more: our 2yo raced over and could not wait to use the cup. I did knock a star off of the ease in cleaning rating, as the metal cups have to be hand washed, and that’s a PITA, but that’s not an issue with the plastic cup (and the metal cup keeps beverages cold). So, it’s overall worth it for me, but I will probably go for the two plastic cups when I purchase more.

Best tumbler for my toddler! He liked the dino design too. It’s leak and spill-proof. Easy to clean.

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.

We love these bottles, I'll definitely be buying more. My kids took the inside straws out as they prefer them that way- still works perfectly (albeit more loudly but I don't mind). So great to find stainless steel bottles for little kids. Also, the no spill works perfectly. Best of all, they are SO easy to clean!

Ambos vasos estan muy bien, los materiales son de buena calidad, incluye un popote de repuesto ademas del que viene en cada uno de los vasos, los dibujos se mantienen con el paso de las lavadas.
