The Phantom is an 18650 mechanical tube mod. The Glas Phantom by Glas Vapor is one of the best mech mods on the market today, but it’s a very different beast to the devices covered by this list so far.

Everything made by Glas Vapor is hand-made in Los Angeles, using only the very highest-quality materials, including aerospace grade stainless steel, titanium, silver, rhodium and even sapphire crystals. The buttons mounted on the bottom of the device, with a beautifully smooth throw are made from custom-tooled aluminum.
