Penny MOD Copper

This beautiful MOD is built in 100% pure copper. This high quality MOD has a dual telescopic 510 adjustable connector, one for the top end and one for the battery end. Since it is full copper, unless you maintain the shine on this device, it will patina. Some people like patina, some people want to retain the shine! Expect great voltage regulation because of copper conductivity.

The Penny mechanical mod is made from a pure copper material. The tube houses a single 18650 sized battery with the top cap being equipped with a telescoping adjustable pin. The bottom firing button is embedded with the "penny" logo, uses magnets as switches for a stiff throw and durability, while the locking ring allows a smooth transition to secure the fire button from misfiring. Both caps in copper contact pins resulting in an excellent  performance.
