Hamilton Devices Shiv Battery

Hamilton Devices is proud to present THE SHIV – our first-ever switchblade battery! The Shiv is equipped with a switchblade mechanism, which offers discretion for the user. Its stealth design makes it an instant hit with all types of people. THE SHIV’s small size makes it portable, but don’t be fooled by the battery’s size– it works with both 0.5 ml and 1.0 ml cartridges.
