The Firefly 2 Top Lid (red) is an official replacement part that is manufactured by Firefly. Because it is an Original Equipment Manufacturer (OEM) product, it is constructed with the same materials and processes used in your vaporizer’s original lid. It also comes with a quartz window, from which you can view the vapor production process. The Firefly 2 Top Lid is also available in other colors and patterns, such as blue, black, gold, jet black, white, zebra and Oak. Getting this product in several colors and replacing your Firefly 2’s top lid every now and then is a great way to switch up your vaporizer’s look.
