A charger is opposed to a charging subject member and charges the charging subject member by generating corona discharge. The dispensing device is a scalable packaging solution including an outer protective housing or shell, optionally a fluid reservoir, and an orifice from which the materials are expelled. The held cards are also held in one, more or each of the other simultaneously displayed hands. The lever arm may be pivotal between an unlocked position to attach the engagement member to the vehicle, and a locked position that causes the engagement member to exert a force on the vehicle to maintain the wheel of the vehicle in the wheel cage.
