These smoke grenades are designed with a composition which produces no external flame and prevents the casing from getting too hot.
 
These Wire Pull Smoke Grenades are simple to use and offer a huge amount of smoke from their compact size.
 
To function the smoke grenade simply pull the ring to the side; what follows is 70 seconds of brilliantly coloured non-toxic smoke. The smoke is delivered from the single vent at the top of the grenade.
