Requested this item for my grandson going into his first year of full days at school. These were bigger than expected which is good. Love the locking lids to keep from spilling however wish they were spill proof with the lid open as well. Cute designs and love that they are sweat proof. Great quality and overall happy.

Zak! design stainless steel water bottle pack is great for children of all ages. First, the bottles are much larger than most of the children’s bottles - 20 oz. It’s especially helpful for older kids and for hot days. Second, the bottles keep water cold all day. We went to a rather hot day at a fair (85 + F), and the water was still crisp and cool after several hours in the sun. Third, the handle is very useful for carrying the bottle around as well as a locking mechanism on the lid that makes it spill proof. Overall, these bottles are very well designed to provide all day hydration and have cool designs that kids like.

My son really enjoyed the Minecraft water bottle! He's obsessed this is the first time he's actually keeping up with the bottle! taking care of it, his Minecraft obsession doesn't hurt and he hasn't lost it yet!! lol I love the spill proof lid since he is kind of a clutz at times prevents me from having wet backpacks at the end of the day it's easy to use lock and unlock my child picked it up quick it's the little touches for me like the silicone rubber at the bottom I have glass on my table so it's perfect preventing accidents my only con is it's not rated for hot liquids but I think that's just because of the design of the lid. The double insulation did keep drinks cold all day though that's always a plus

The 20oz Minecraft Zak duo packs were a great product for kids who are on the go. These containers are a great size for backpacks and holds close to the 20 oz of water. The lock features were a great surprise to assist in accidentally spillage. Currently, there have been no spills. The character images are vibrant with rubber bottoms that act as aound absorbers. Overall, a great start of the school year product!

These are really great cups!! First of all they are just super cute for kids. The colors are vibrant and the material is very durable. The lid has a little lock mechanism that will help with spills. I can see my grandkids using these for a long time and feel confident that these will hold up to the numerous drops, rolls and throws the boys will put them though. In addition, the Sonic design is their favorite!!

These Zak cups are SO cute and sturdy. They’re going to be great for my daughter for school and traveling. The lid is great, it can be easily locked and unlocked so that there’s no spills at all. It definitely keeps drinks cold for a while! The fact that it’s a straw system too is something my daughter loves. I would definitely recommend these. We got the Hello Kitty designs and they’re adorable!

My daughters got the hello kitty design of these water bottles and I don’t think I’ve ever seen kids so excited about water bottles. They’re large enough and perfect size for a child (mine are 4 and 6). They’re super cute in design and quality wise they’re great. The spill proof design is also great for us parents. I love these

The Hello Kitty water bottles set stands out with its vivid, eye-catching designs. Each bottle features bright, cheerful colors and adorable Hello Kitty graphics which I love as a collector. The high-quality, bottles ensures durability and resilience, making the bottles ideal for daily use. The vibrant colors are not only attractive but also resistant to fading, even with frequent washing. The sturdy construction means these bottles can withstand drops and rough handling. This set combines aesthetic appeal with practical durability, making it a stylish and reliable choice for Hello Kitty fans.

These are great so far for my elementary kiddo's school water bottle. Good capacity, fantastic insulation! Design work is done well, I think it will stay put for a while through use/washings, unlike most insulated tumblers we've had in the past.

Spectacular cups. Nice size, doesn't leak (when top is closed/secured), really solid construction; they're really quite heavy. Kiddo loves 'em, and they seem like they'll keep the drink cool very well throughout the school day.
