These grenades are made in the form of glass flasks. Model 1H is a single container; Model 2H includes an inner glass tube filled with a solution of calcium chloride. The body of each grenade is filled with titanium tetrachloride which vaporizes, upon contact with the air. The calcium chloride permits the second model to operate at low relative humidity, whereas the first model produces a thin fog unless the air is quite moist. Both models discharge upon impact with any hard object.

The prototype of this grenade is comprised of the body of the smoke hand grenade 39 with a synthetic resin adapter to hold the B. Z. E. igniter. The Model 41 is of similar construction but the body has been modified so that the igniter fits into a small central neck without the use of an adapter. There are only two smoke holes instead of eight. The friction igniter operates with a 4-5 second delay, setting off a 2-minute smoke discharge.
This grenade closely resembles the high explosive stick grenade 24 in external form and size. However, instead of the high explosive filling this grenade is filled with a smoke mixture. There are eight holes in the base of the head through which the smoke escapes. The handle has three horizontal corrugations at the screw cap end to assist in differentiation by touch. Upon activation, smoke is emitted for a period of two minutes, forming an effective screen for machine gun nests and pillboxes.
