A very quick solution to fix a minor puncture. And it comes in a small package. With this set of seven self-adhesive Weldtite Red Devils patches and an emery cloth, you can make lightning-fast repairs after a puncture while taking up a minimum amount of space. It is easy to calculate how short a time it takes to roughen the surface of the inner tube, clean and apply one adhesive patch. That's all, just put the tire on, inflate and keep riding.
