The Original Wire Pull™ Smoke. Available in 9 different colors, WP40 is our work horse of the smoke grenade family. Simple to use and a large amount of smoke for the compact size of the device.
To function the smoke grenade simply pull the ring to the side. What follows is 90 seconds of brilliantly colored, non-toxic smoke. Smoke from the WP40 is delivered from a single vent at the top of the grenade.
