![Replacement or additional caps for BackBottle](http://backbottle.com/cdn/shop/products/IMG_2826_large.jpg?v=1564415985)
Our cap is 53mm in diameter, so your other bottles will very likely NOT fit on our bottle. Pick up some extra caps now just in case you lose 1 in the future.
Nothing different than the other caps, just more of them. This product is ONLY for additional caps.
