Enola Gaye WP40.
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.
