Our custom bkr Straw Cap is made for use with our bkr Soft Silicone Straws only (no rigid straws please, it’s a safety thing). It’s made with the same BPA-free, phthalate-free food-grade polypropylene as the caps you know and love and has a clear silicone valve to hold your straw.

To use it you’ll first screw the cap onto the bottle, then insert the straw through the clear silicone valve. This cap is splash resistant. It will keep your water in its place during light turbulence on a flight somewhere fabulous, but if tipped over in your bag some water may spill out. It’s dishwasher safe on the top rack like everything we make, and the valve is removable so you can wash all the parts thoroughly for zero yuck.

*Sheer white.

It’s just what I needed for work, where we’re not allowed to use reusable drink ware due to COVID. Because I never drink directly from the bottle, I can refill the bottle from our water cooler without risk of contamination.

250/500ml straw cap

I haven't received the 250/500ml straw cap yet. BKR sent me the 1 liter cap instead. When i flagged this glitch, they have jumped into action and the correct one is on its way. Their customer service and commitment to keep customers happy deserves a FIVE STAR. As a BKR customer, I am passionate about the brand. All my good friends in Dubai have been gifted a BKR bottle for their birthdays. While I wait for my 250/500ml straw cap to arrive, I've already placed two new orders for bottles. And I'm nevertheless enjoying the 1 liter straw cap too. A team like BKR deserves to stay in business because of the joy they spread in this world! If you aren't drinking out of one, you're missing out so step on it, and thank me later

Game changer

Now that I have the straw caps, I drink so much more water. I’m so happy BKR finally designed straw caps.
