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 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’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 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!

Please bring them back. They are my favorite for my grandson. They are great and just the right size.

It arrived in a pretty box. The cups look very well made and the design was so cute. It will be great to be used for young kids long time since it is made in metal. The top has built in straws but spill free. Size is good for toddler to young kid even through elementary schooler. It is a good tumbler!

My girls screamed and jumped when these cups arrived! They loved the princess designs, while I loved the tight fitting kids with guilt in straws! These cups are leak proof, insulated, and anti-microbial since they’re stainless steel! Win win at our house!

We love theses water bottles, my kids love the Design on them. Plus it is stainless still so it keeps your start colder for longer. It is also, spill proof which is so big when you have little kids. Love that it is also a straw cup it makes it easier for my kids.

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!

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.
