Reflex is wrapped outside with a durable bag, which is easy to tear open from a little jag on its upper-right corner. Inside you'll see a ration of Reflex beads within a special thin plastic film. Simply throw that inner bag inside the tire, once the tire reaches the speed of 50km/h the bag will break open and Reflex beads will disperse inside the tire.

It's not convenient for you to remove your tire sometimes? NO PROBLEM! Reflex offers a special Injection Kit, with which you could easily inject to the beads in from the inflating valve.
