510 to eGo adapter
$3.99

Want your eGo battery that lacks 510 threading to play nice with a 510-threaded tank?  Or what about 510 device that doesn't have a raised crown.  Here's the answer.  This shiny silver adapter will do the trick.  It will also add extra height to a thread or protect the underlying thread of an expensive device from stripping or the occasional e-juice leak.  Don't forget to check out the supply of beauty rings we have to cover the adapter and keep your device looking sleek.
