Water Bottle Straw Cap

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. Available in 2 sizes: - "Little" to fit the "Little" or "Teeny" size bkr water bottle (250/500 ml) - "Big" to fit the "Big" bkr water bottle (1 L)
