Demi sheer deep vampy blood burgundy
Double Wall Glass + Silicone Tumbler

Your insulated soulmate.
Exquisite, elevated, and transformative. Drinking from the bkr cup is sensory nirvana. It’s like the perfect t-shirt of tumblers. It’s soft and pretty, it feels right and fits right, you want it in every color, and it becomes an extension of you. 100% dishwasher safe, microwave safe with the cap off, grippy pretty silicone, clean, clear, never looks scratched, peeling or rusty, sets down silently, never imparts weird, metallic taste or last-drink’s flavor. Keeps cool things cool + hot things hot.

Should I get a cup or bottle? 
You need both! When you need sustained temperature stability, thermal shock resistance, splash resistance, a wide mouth for ice, and the most exquisite sensory experience, this is your new baby. When you need break resistance and a 100% leak proof cap it’s the bkr bottle you want.

This size is called a Demi. It holds up to 500mL (16 ounces) and fits in most cupholders. Perfect to keep a big iced beverage cold poolside, a grande cup of coffee, and two-thirds of a bottle of wine.

Valentina ColorInspired by a muse who lives her life in full-bleed, a maximalist in spirit but someone you really need to meet twice, black hair and bitten lips, extra but a little self-conscious and shy in person, an ambivert with an asmr voice, allergic to small talk, always politely honest, and when asked her idea of heaven, she answers: an Italian velvet couch in an ebony room filled with books arranged by color, black baccara roses, the smell of santal 26, and a big slice of cake. But ask her again tomorrow, her answer is never exactly the same twice.

Directions for sleeve removal:

  • Release the tension between the glass and the sleeve by running your finger or something like a plastic chopstick at the top between the glass and the sleeve before removing - never force it as it could break

To keep your cup looking like new:

  • Immediately rinse after use before placing in the dishwasher
  • Wash all pieces of the cap separately
  • To remove gasket pull down from the flat area above the K in the bkr logo on the underside of the cap
  • Treat your bkr cup like a fancy wine glass (gently) and your gasket and straws like your teeth (clean them or they could stain)
  • To remove stubborn smells or tastes from straws, bake at 250 degrees for 30 minutes, smell carefully, bake for another 10 minutes if smell persists.

Purple-y brown, not the color I was expecting

I like the glass container and it does keep my tea hot for awhile, but not too hot, which I like, but I wish they put a glass lid on it sealed with silicone because I do not want to drink out of that plastic hole it has. To drink I just remove the whole top and sip from the edge. I hope they sell a glass top for this in the future.

love but already broken. 😞

Love the idea of these cups. I bought a lavender smaller size and kept waiting for this color to come back into stock. Finally got my hands on this and not even two weeks into using it, it’s broken. It fell over on my kitchen counter. it’s really irritating to me that I bought this to replace the smaller one that shattered. so now I’m just left with silicone sleeves and the lids.

Fantastic fabulous phenomenal!

I was hesitant to purchase this—I had used borosilicate glass in the kitchen and broken it, multiple times. I read the reviews and was concerned that some found the glass held on to odors from their drinks, found it did not keep drinks warm for long, or had issues with cleaning. I purchased mine on sale, having low expectations. I loved the sleeve color and could use it on my Demi bottle if it was a dud. Well, of course bkr knocked it out of the park!! This was the finest travel mug I’ve ever used—kept my TCM herbal tea hot for hours, did not retain scent of tea once washed, beautifully and thoughtfully designed, just a complete pleasure to use. My third time washing it, I accidentally bumped it into the sink, where it fell face first and broke. Bkr very kindly sent me replacement glass. I would say these only need to be babied when you clean them. Otherwise, it stood up well to me accidentally slamming it on its side. Just a phenomenal product!

Dangerously Broken Within 2 Months

What's wild is that I have a second demi cup in the River color that I've had since they were released and that one is still going strong despite the same treatment. I took a sip from my iced latte the other morning only to get a mouthful of glass - the bottom of the double-walled portion broke but left the rest of the glass intact, so I had no idea until it was too late.

Perfect, except.....

I've had my demi bottle for 2 months now and I only use it for my iced coffee. I don't even use it every day but I love using it because it makes the perfect amount of coffee. Unfortunately this morning I went to use it and found that the top of the rim was cracked making it unusable.. it had been sitting on the counter since I last used it. I had cleaned it out before bed the night before and no one touched it since then.. Thankfully I had bought a second glass because I read some people say they are fragile, but all the ones that I had read said they dropped it. I never dropped it.. it shouldn't have broken.
