First off I must say, shipping was so incredibly fast! When I order something I'm excited about, I don't like to wait too long and Whiterock did not disappoint. When I took the tumblers out of the box, the colors are so amazing! So vibrant and bright like pictured on their website. I love the texture of the tumblers as well and of course I instantly did a leak test, and it didn't leak AT ALL! The lid is like a snap lid that has a great seal. The lid feels like it doesn't go on that well if you put the lid on with the snap piece down, but if you lift it up first and then put the lid on, it goes on a lot better. This tumbler keeps my cold drinks cold and hot drinks hot for HOURS! I will for sure be purchasing more of these tumblers and checking out more of their products. I am very impressed and better yet, it's a CANADIAN company 🇨🇦 I would 100% suggest you get one and test it out for yourself.
