The Firefly 2 Top Lid (white) is an Original Equipment Manufacturer (OEM) part, and an official replacement product for your Firefly 2’s top lid. Like the original top lid, this product is constructed from magnesium alloy. It is also coated with a layer of borosilicate glass inside. Its quartz window will even allow you to look at how the vapor production process happens. The Firefly 2 Top Lid comes in other colors and patterns, too, including blue, black, gold, red, jet black, oak, and zebra wood. By keeping a few spares of this product, you’ll never have to worry about a missing top lid.
