This micro-sized lock pick set weighs just 0.4 ounces and measures barely two inches long. But it can be concealed and carried in almost any place imaginable, including inside the Hollow Lighter Dead Drop Kit, as shown here (sold separately).
The kit fits snugly inside a small vinyl pouch to eliminate the sound of metal-on-metal while moving, and contains the following tools:
#3E Small Diamond
#8 Short Hook
#6E Euro Wave Jiggler
Tension Tool (separate)
Some of the tools can also be used to facilitate escaping from restraints in unlawful confinement scenarios, especially when traversing dangerous and non-permissive environments outside the continental United States. This kit could one day save your life. Just ensure that if carrying it or using it, you're aware of all applicable local, state, and federal laws. And make sure to leave it in your checked luggage if flying somewhere.
