Awesome cup!

This is the perfect cup in my opinion. It is right-sized for the hand, the straw is wide enough, and the glass insert fits snugly. It has won it's spot as my go-to iced coffee cup. The customer service from the company is phenomenal. I had a minor issue that was addressed quickly and resolved.

Finally found a glass tumbler for my cold brew!

It's hard to find glass travel cups but this one is fantastic. I bought it in three colors- vanilla, matcha and glacier. It stays really cold and it's easy to clean. I'd love to see a smaller straw/top option cause i'm not a fan of big straws, but I use my own skinny straw, it just doesn't seal the hole up. All around great tumbler! I'll buy again.

Really nice color! Unique cup.

It's small so the drink goes quick at work, I have used big and little cubes of ice and bigger last longer but have ice left either way. The design is nice, I can just wipe clean the metal sleeve.
