BBTANK Key Box Plus 510 Battery

Introducing the BBTank Key Box Plus, featuring an upgraded rendition of the popular BBTank Key Box. While maintaining the stealth innovating key fob chassis, the Key Box Plus is equipped with a 510 threaded connection that can be flipped close to hold the connected cartridge or opened whenever it is being used by a single fold button. Folding the cartridge open or closed also determines when the device is on/off (device being on by screwing the cartridge onto the battery and device being off by folding the cartridge back into the battery).
