Zipper Pulls The Schrader bicycle valve, while being an excellent device to maintain your tire pressure, doubles remarkably well as zipper pull. This item was designed out of the necessity of a zipper pull for our Messenger bag line. With a bunch of leftover valve stems, some sweat, and a bit of imagination, we came up with a useful pull easily affixed to most zippers. Put it on your luggage, your rain jacket or your key chain, but we don’t recommend your fly. Buy Now. Read the FAQ.
