Special order items take longer to ship

We want to make extra-sure you realize that you've added a special order item to your cart. These items take a little longer to get to you because we have to order from the manufacturer first. The "Est. Ship Date" is the date we expect items to leave our warehouse... so add your chosen shipping speed to see when it will show up at your door.

Product Reviews
Rated 5 out of 5 by from The Perfect Cap! This flex cap is perfect! It screws on and off just like a cap should. It keeps the water in and everything else out. I really don't think that there is anything else I could hope for from a standard mouth flex cap. Perfect!
