STRAW CAP 250/500mL (8 OZ / 16 OZ)

47 reviews

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.

Love it!!

My only regret is not purchasing this sooner. Was able to use my existing glass straws from Amazon with it. So happy.

Great Straw Caps

Really like these caps! When the straw is in or out, the cap keeps the bottle closed as if it were a solid cap! The cap with a straw is a very pleasant way to drink from the bottle and helps when tipping the bottle up to drink is difficult. Thanks!

Love these

We have so many straw caps in our house now and we all love them, from my husband and I to our 3 and 1 year olds!
