Love it!!

Love my tumbler!!!

LOVE LOVE LOVE!

I love my new brute lune 40 oz tumbler. I never leave home without it. It’s perfect!

I love this cup

My new favorite

I absolutely love this Tumblr. Trust me… I have bought all of the other brands that claim to be leak proof and they are not. When I found found this Tumblr. It was my hope that it would in fact be easier to open at the top without the seal, needing to be run under hot water. This Tumblr is everything I want and more. I love the dual spout access. I love the idea of a metal straw, which of course keeps everything nice and cold when drinking. The Tumblr stays extremely cold and the ice intact for hours and hours. My only wish was more variety of colors.

Love It!!

Love it!

This has br one my favorite cup. And i hace them all. Stanley, rtic, Brumate, Hydro Flask and every off name brand on the market. The BriteLune keeps my drink cold and holds ice for 2 days and is not heavy like the other ones. The only thing indont like is the Pepto-Bismol pink. But that’s the only color that was available when I ordered.

Amazing Tumbler

The quality of this tumbler is amazing! Easy to clean! Keeps drinks very cold! I love the straw option! The color is so fun

Great cup, great color!

The color is so much prettier than expected and it came on time.

Best tumbler I’ve ever owned!

I’ve tried them all—Stanley, BrüMate, Contigo—but BriteLune wins! It’s 100% leakproof (yes, actually!), and the 2-in-1 lid lets me switch between sipping and using a straw.

It keeps drinks cold for 30 hours, and the hot pink color is stunning—I get compliments everywhere! If you want a tumbler that’s stylish, practical, and spill-proof, this is it. Obsessed!
