I have several sets of these for the grandkids. They are spill proof which is awesome. They also keep beverages cold. Just so you know, you have to suck pretty hard on the straw to get the fluid out which is great for toddlers learning how drink from a cup. They can't get too much too fast. This also helps to prevent guzzling. You can go to the Zak website and order extra straw sets if your little one is a chewer. Highly recommend these cups. They are cute, spill proof, and keep drinks cold. Can't beat this price either!

I’ve been searching for a two pack of these tumblers for my daughter for a while but all I could find was a plastic set. Then this came along. I saved one for her birthday and gave one to her now. Minus the fact that the rubber band comes off the top, the design is great. It does leak sometimes though, not terribly, just enough to question where the water came from. It keeps her water cool and it’s easy to clean In comparison to almost EVERY kid cup out there. I’d definitely buy more!

I love that these are stainless steel instead of plastic. They’re a lot more durable and hold up much better with my kiddos, that tend to crack the plastic ones in no time. They are easy to clean, and my kids always request to drink out of them, since Spidey is their favorite.

I recently purchased the 2pk Minnie 12oz DW SS Vac Kelso Tumblers, and I couldn't be happier with my choice! These tumblers are not only adorable with their Minnie Mouse design, but they are also incredibly functional. The double-wall vacuum insulation keeps my drinks hot or cold for hours, making them perfect for both coffee in the morning and iced drinks in the afternoon. The size is just right for on-the-go use, and the sturdy construction ensures they can handle a bit of rough treatment. Plus, the packaging in a remailer makes them a great gift option! Overall, I highly recommend these tumblers for anyone looking to add a touch of fun to their drinkware collection!

I love these cups and my kids love it more. My 5 years old was excited to have a new cup for school. No leakage what so eve, it does conserve the water temperature, I only try it for cold water by the way. It is easy to clean because my baby enjoy cleaning her own cup. My suggestion is that a little straw cover for sanitation reason will make this cup the best I ever used.

My 2 year old is obsessed with these cups! The cups are extremely easy to clean as the straw on the inside comes apart, so you can use a straw cleaner easily. They are also dishwasher safe, which is always a plus. The straw on the outside is squishy and not hard, so that is a plus if you have a child that always bites straws. I also LOVE that these are leakproof. 10/10 recommend!

My child absolutely loves these cups! I constantly have an emotional support cup of ice water with me everywhere I go and now my child can have one too. They keep their drink, icy, cold, and refreshing in the summer heat.. With it being spill resistant, and also kid friendly, you cannot beat it.

These cups are vibrant and durable! They seal so no soils and are insulated so the kids drinks stay cold. Cups are small enough to fit in a car seat cup holder but tall enough to hold plenty of Juice. Great price and value!

Too heavy for little hands Topple over easily But what was really frustrating is that these cups spill more than the other toddler cups. Supposedly this brand was “no spill,” but when I accidentally knocked over a cup water seeped through a sweater that was nearby so quickly. No way am I going to give my little ones to take to school and then their backpacks will get wet.

I have bought this brand of cups before but never the metal ones. These leak out the sides no matter what I do. Super disappointed about these because we love bluey.
