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!

Great, Sturdy Cup

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.

Bluey cups for the win!

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!

Easy to clean and love them

We have these for our boys and daycare. I LOVE THEM. Easy to clean. Keeps drinks cold for longer. And of course the kids love the designs. Obviously the fact that it is easy to clean is a huge deal for me. I’m cleaning all the time with daycare. So if it is easy. That’s a win for me.

Beautifully designed and Quality material

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.

Great product!!

I’ve received the Zak Designs 12-oz. Stainless Steel Double-Wall Tumbler for Kids with Antimicrobial Straw, 2-Piece Set two weeks ago. I couldn’t be more happy with the product. It’s winter, it’s come at perfect time. I recommend this product to all my friends and family.

Zak Designs 12-oz. Stainless Steel Double-Wall Tum

I had ordered these for my grandchildren age 2 & 8. At first I thought they might not like them, but they both loved them. They easily fit in the car's cupholder and the straw make it very easy for them to drink. They loved the Star Wars design and I love that they don't spill. Great product.

Great Tumblers for Kids

These cups are cute and funtional! You can fill it with water, hold it upside down with no leaks even with the straw in. My two-year-old granddaughter loves that the cup is just her size. I like the silicone straw because its SUPER durable! At preschool, the cup gets tossed around a bit and it no worse for the wear. The Little Princess print is adorable! It is very easy to clean and not stained by juices. I have no complaints.

Very cute set of cups

Very cute stylish cups. The ones I got are different than what was pictured. Mine were also already unpackaged once as they were out of the plastic and it was just shoved in the box, however they didn't appear used. They do state they are leak proof. While tipping them they do not leak, they will leak if carried upside down or shaken as can occur with any toddler, but no where near as much as other cups. I shook the cup upside down and got some water out, but not just pouring out as we have all seen with other cups. Inside is stainless steel but the lid and straw are not, which I like. I am not a fan of when the straws are also metal, especially for kids.

Couldn’t be happier!

My son is tough on his cups, as most busy toddlers are. We go through so many cups a year due to the seals failing, the straws falling apart or being dropped and the cup cracking. These cups are so heavy duty, I don’t see them failing us anytime soon! I love that they are double walled for insulation during the summer months to keep your drink cold. The straws are much thicker than the competitors, making them less likely to leak with minor chewing.
