Sturdy for toddler

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!

Adorable and Durable!

These cups are the best! They keep drinks cold and with ice for awhile! I’m not positive they are “leak proof” as stated. It could just be my kids that are constantly dropping them! The designs are cute and they are very durable. Just make sure to wash the plastic ring under the cap!

Happy new cup day!

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!

Spill proof

I got these for my 4 year old and thought he might be a little too old for them, but have found them to be the perfect water bottle to use around the house because they are spill proof. He loves the straw and it has a mechanism that prevents it from leaking if it tips over. The Spidey and Amazing Friends theme was the perfect choice and this is now his go to choice of cup. He can even easily screw on the lid by himself.

Minnoe Tumbler

These tumblers are so practical. First of all, they are leak proof, which is key for any kid’s bottle. The Minnie design is perfect. Keeps water cold for a long time. It’s also top rack dishwasher safe. What’s not to love?!

My little lady loves her princess cups. I do too.

The no spill technology is absolutely amazing. My two year old can fling it, throw it, bowl with it And there are no messes anywhere. She loves the princess designs and it washes well in the dishwasher.

Spider-Man tumbler

My son really likes these. It keeps ice well and he has drank hot chocolate out of it also. He takes them everywhere. I would have liked a couple extra straws with the set in case he leaves milk or something out of it.

Not a fan

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.

Disposable

I bought 3 sets because they were on sale. well, each bottle did not last for a month. They mold so easily , (putting in mind I only put water, and they are hand washed daily and in the dishwasher weekly) . And the silicone straw as well, as seen in the picture, the are shocking hazard , moreover, i don't think they are edible (hopefully not toxic if a kid swallowed it)

Leaking

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.
