The Vapor Giant V2.5 Mini Mech-Mod
Made of high quality brushed stainless steel, it fits perfectly with Vapor Giant's 23 mm atomizers. The side button can be locked, which prevents accidental firing.
It has a level of versatility that is difficult to find in any other mods. With extension covers, it can be operated with one 18650, one 18500 or two 18350 batteries.
