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

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.

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!

These cups are my favorite cups for toddlers. I prefer the metal ones to the plastic ones because they keep the drinks cold. My son loves all the different designs- we have several. They do not leak and it is hard to find a cup that doesn’t leak! Super easy to clean as well.

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.

I knew I wanted to go to straw cups after bottles when switching to whole milk. These cups are fantastic. They don’t leak and are easy to disassemble for cleaning. I bought two sets and send two of these cups and one bottle in our transition phase and eventually will send 3. My 12 month old is able to hold and drink out of thaws just fine. I normally do milk in the translucent cup and water in the stainless steel cup at home. The stainless keeps ice all day to keep his water cold in the recent heat we’ve had.Update: today while washing the cups I noticed something weird around the seal in the lid. There was mold growing in it. I wash his cups every night and let them dry well before putting away. Make sure to take the ring in the lid out for washing. I was able to pop it out with a straw cleaner.

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.

These are spill proof, the color hasnt faded at all..they are super cute and durable and they function well once the kids figures out how to use it. They are also great cause they hold temperature. Whether warm or cold they will lock it in for a while.

I love the design of the bottles and how there’s two of them for different functions. The thermal cup is great for maintaining the milk from warming up. The other bottle is great for water and juice( at least for my preference of use). It’s a great size for my toddler as well, it brings an extra straw and it’s a great transition from the bottle to sippy cup. It can be a bit leaky if you shake too hard but not enough where you’ll freak out. Overall happy with this purchase.
