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!

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 .

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.

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 was so excited to gift these adorable water bottles ri my hello kitty fan. However, once I washed and filled them up we found that it was very difficult to pull the beverage through the straw. By the time I finished the first fill the floor of my mouth was sore from pulling so hard on the straw. They do not leak, so that is a plus.

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.

Great product! Extremely well made and heavy materials. We have used them daily for almost a week and they wash and use without issues. Fit in both vehicle cup hokders without problems. We will totally recommend to all our friends and family!

Great cups, great price. Always need an extra cup so glad these come in a 2 pack. Do a good job at keeping drinks cold and the handle makes them easy to grab! Would love even more design options in the future!

This is a great cup for kids. So sturdy and well balanced. The graphics are clean and dishwasher safe is always a plus. Great for keeping drinks cold for a long car ride or outside for hiking or other sports activities.

Lightweight and easy to carry. Keeps liquids nice And cold. The size fits one and a half water bottles. It comes with a straw and easy to pull open the straw , my 4 year old uses for school. Fits in small backpacks
