These carbon fiber smoke poi, hold Enola Gaye WP40 smoke grenades and come in a wide variety of colors plus leash and handle options. The tube is custom made CF with a built in set screw to hold the smoke grenade in place. Each poi with leash weights about 5.5oz (smoke bombs are an additional ~4.5oz each). Smoke bombs tend to last about 1.5 minutes.

The sale and shipment of these smoke grenades has been banned in the state of MA, so Dark Monk is no longer able to sell them. They can be purchased in the US from Smoky Bombs and directly from Enola Gaye for some other countries.
You must get the Enola Gaye WP40 size smoke grenades for them to fit in Dark Monk's smoke props.

Remember to pull the wire pin out of the grenade sideways, not upwards. MAKE SURE to tighten the screw and test the smoke bombs fit before pulling the pin.
