Must have!

How cool is this tumbler!! It'll keep your drink cold for hours and hours. I like how the lid screws off and on because sometimes the seal can wear down. The tumbler is also very lightweight. It comes apart to clean easily. Also, if you're kids chew straws, this one is silicone.

Very nice

I love this cup, its perfect for my daughter shes having a kpop demon hunter themed birthday party. Its good quality and has a nice shine to it. I got her some stickers to put on it to make it more fun for her (shes 5) . I think she will be happy to have a water bottle thats kind of similar to one i have. She drinks lots of water so this is perfect for her.

New favorite cup

First off, we're huge Harry Potter fans in this house so the cup is everyone's new favorite. The color is a cool toned purple and gold etched writing, it's beautiful. I love that the straw portion that's outside of the cup is soft because I do have two children and I know they won't hurt their mouths on this cup. The outer, soft part of the straw can be removed for cleaning. The inner portion of the straw also detaches for cleaning and is wider than the straws on any of my other cups. It's dishwasher safe which I love as a busy mom. It keeps ice water cold through the day which is a must in AZ heat. I wouldn't say it's 100% leak proof, if tipped over it does leak.
