This pack of 30 tire plugs works great as a refill for our reamer and plugger kit. When you get a puncture, don't despair! Just insert the reamer into the offending hole a couple times to clean it up, ensuring that the plug will hold. Then, thread some of the included plugging material through the eye of the needle. Jam the needle in the hole, pull it out, and voila! No more puncture. No more heartache.
