Your insulated soulmate.
We’ve combined our exquisite and elevated cup with our perfect cup straws. True love. 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.

You can sip hot drinks from the opening or use the soft silicone straws for iced-beverages. The straws are custom designed to fit the up perfectly: they are just the right balance of firm and soft and they have a slightly angled bottom so they never suction. This cup is splash resistant with the cap on and button in, and all parts are uncomplicated and clear so you can wash them thoroughly for zero yuck. Yes, we've thought of everything. Whether you’re heading somewhere fabulous or cozy at home, you’ll want this with you all the time. You can buy all the parts separately too, but our sip kits are at a value and include everything you need.

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.

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, the cup is your new baby. When you need break resistance and both a 100% leak proof cap and splash resistant straw cap, it’s the bkr bottle you want.
