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 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’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!

These are the absolute best tumblers that I have come across for small children. The design is beautiful, pretty colors and very appealing to my granddaughters. The tumblers are made of great quality materials, with a soft straw for little mouths and sized perfectly for little hands. They are quite easy to clean and dishwasher safe. Tumblers are also vacuum insulated which keeps drinks cool. Great product. I would definitely recommend.

Truly love the Zak cups especially the metal ones! These are actually leak proof and better yet, they come as a 2 pack! I love the flexible straw so if my toddler runs with it he won’t get hurt like other cups. The designs are so cute! These are the perfect milk cups for us and use them daily!

My son really likes these paw patrol cups. He likes the design. I like how they are spill proof and can go in the dishwasher on the top shelf. They are 12 oz which is a perfect size for a 5 year old. Since it isn’t too big it fits in a car cup holder and the side of his backpack for school. I like how it’s only two pieces, I seem to loose pieces to water bottles then I can’t use them. It would be nice if they came with extra pieces. Overall a great product.

My grandson loves these cups. He just turned four. I have not had any leakage when dropped, and it keeps the cold drinks cold. He sucks them like a straw. I hand wash, and use a bottle brush to clean the straw part. It says the top part is dishwasher safe, but I clean the detached straw, and straw opening on the lid with a bottle brush. You could use the dishwasher for sanitizing.

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.
