Zak designs produced fun looking and easy to carry tumblers for keeping your favorite drinks cool. The built in straw allows you to drink easily with a flip. The product handle makes it easy for you to carry the tumblers when full of liquid. Only time will tell how the straw will remain clean, but I’m sure a straw cleaner is a must. Excellent gift for young elementary age children .

Very cute thermoses that are designed with a character so popular with young girls! The design is adorable & trendy for sure. The 20 oz size would definitely be adequate for young girls, probably a little too small for adults. Feels durable without being too heavy or bulky. Nice insulation to keep cold drinks cool for a bit. No problem with leaking so far. Overall, would recommend for tweens & teens who adore Hello Kitty!

Best On-the-Go Tumbler! I am obsessed with these tumblers! I actually have the Minecraft version in green, and it is easily my favorite everyday cup. Not only does it look awesome, but it works extremely well. A few highlights: Insulation: It keeps my drinks ice-cold for such a long time—perfect for hot days or long shifts. Design: I love the built-in straw! It makes it so easy to stay hydrated without having to fumble with a lid. Tesla-Friendly: For anyone with a Tesla Model Y, this fits perfectly in the cup holder. It’s hard to find good tumblers that don't rattle or feel too big, but this one is a great fit. Durability: The build quality is top-notch. It’s sturdy, holds up well to daily use, and feels like it’s built to last. These make great gifts for kids and adults alike. Whether you're a Hello Kitty fan or a Minecraft gamer, you won't be disappointed!

These tumblers arrived in great condition! They're the perfect size for my 9-year-old, who uses them frequently for soccer and outdoor events. I pack them with plenty of ice, and drinks stay cold for about 12 hours outdoors, and about 16 with indoor use.

I really like this 2-pack tumbler set because it feels both useful. The tumblers have a clean, modern look and feel solid in hand. They do a nice job keeping drinks room temp longer than a regular cup. The flex grip is a nice touch and makes them comfortable to hold. The 20 oz size is great for water throughout the day. They seem well made and good for everyday use at home, work, school or on the go. The design is simple but still stylish enough to stand out. Overall, it’s a dependable tumbler set that I’d be happy to use.

Picked up the Stitch tumblers for my Stitch-loving 9 year old and she really likes them. It was nice coming in a 2 pack so she can alternate which one she takes to school. They seem to function as it should and doesn leak, so thats a winner with us!

The design on these tumblers are beautiful, the size is perfect and it keeps my girls drinks cold for hours. Not only are they super cute but they are high quality, it has become her favorite tumbler.

Water bottles are durable and keep drinks cold for about 8 hours. The designs are cute and finish on the bottle is glossy. The handle is a great feature and is very durable. Straw removes for easy cleaning as well.
