  • Better than a Stanley!

    I love this cup, it's well made, stylish, convenient. I always hated the random flopping around straws in a Stanley, this one has a rubber thing holding it in place in the CENTER of the cup, not a random straw on the side like other models.

    - Paula W.

  • Almost Perfect!

    This tumbler checked most of the boxes of my dream cup! I love the valve-type straw hole that seals around the stainless steel straw. Because of this, the straw does not require a stopper so that when I inevitably have to share my cup with my kids, I can remove the straw quickly so that they can drink out of the regular spout.

  • Stays Cold All Day — Great for Work or Travel

    First things first, this 40-ounce tumbler kept my tea iced and cold all day. I filled it at 7 a.m. before work and twelve hours later, the ice was still there!
    The stainless steel straw. I’ve never used one before and was impressed. There was no strange taste and it’s very sturdy.
    - Pam S.

  • I highly recommend this tumbler!

    I bought this to replace my broken Thermos, and I’m really impressed! I use it every day for work and the gym, and it’s been great. It keeps my tea hot all day while I’m teaching, and I don’t have to worry about spills. I filled it with iced tea at the state fair, and even in the Florida heat, it stayed ice cold all day.

  • Incredible quality and value.

    What a nice tumbler for the money! I love the extra accessories and it keeps my water cold all day. Leak proof and love the pink color. Very happy with it.
    - Kate S.

  • Very Durable and beautiful color!

    Perfect size and color! Easy to wash, you get two cover tops, and straw cover. It will make a good gift too. I got this tumbler to help me stay hydrated this summer.

FAQs

How long does it take to ship the product?

We offer domestic shipping in USA. All products are stocked in USA and are delivered via Amazon or UPS within 3-5 business days.

What makes BriteLune better than other popular tumbler brands?

While others cut corners, we listen to real user frustrations—and fix them. From impact-resistant lids to real dual-temp compatibility, to top-tier steel and beautiful finishes that won’t chip or scratch—BriteLune is built for everyday heroes who deserve better.

Does it keep ice cold all day or is that just a marketing?

Yes! Thanks to our double-wall vacuum insulation, it keeps drinks cold for 24 hours and hot for 12. We’ve tested it ourselves—and made sure it performs better than most tumblers out there. Just make sure the lid is fully sealed!

Can I use BriteLune for both hot and cold drinks?

Absolutely. Our tumbler is dual-temp engineered to handle piping hot coffee (up to 12 hours) and icy cold water (for 24+ hours). Unlike other brands, we don't hide fine print—you can safely enjoy both without compromising performance.

Does the tumbler leak or spill when tipped over or dropped?

BriteLune tumblers feature a dual-locking mechanism that’s been drop-tested (yes, even on carpet!). Flip top lid is 100% leakproof, perfect for your bags. And even when you are using straw, the spill resistant-seal holds strong.

Does tumbler rust or leave a metallic taste?

Never. BriteLune is made with premium food-grade 18/8 stainless steel—non-toxic, BPA-free, and rust-resistant. Plus, we coat the interior with a non-reactive finish so your drink stays pure, odor-free, and great-tasting all day.

Will the color or paint chip off?

Nope! We use high-quality, durable powder coating that resists scratches and chips. Whether you’re using it daily or keeping it in your car cupholder, it’ll still look great.
Additionally, our tumblers are also dent-resistant.

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.

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.

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!

Durable and Leakproof!

This tumbler is super durable and doesn’t leak. I’ve taken it everywhere—on hikes, to work, and on long trips—and it hasn’t let me down once. Plus, it looks cute with the bright color!

A more Stylish Alternative to Owala

I love my Owala, but BriteLune gives me the same durability with a much sleeker look. The bright pink color is stunning, and it keeps my iced coffee cold even longer. Definitely my new favorite tumbler!
