The Kayfun Lite 2019 window in PMMA (Fire) is included with each atomizer. If you wanted to change the color to Ice from Fire, simply swap out your window with this part.

The Fire version is made from polyetherimide or PEI. A high-tech synthetic material that is designed to withstand e-liquids that may crack other tanks.

The Ice version is made from polymethylmethacrylate or PMMA. This is an acrylic glass that has a "frosted" look and changes to crystal clear when liquid is inside the tank. This tank section is not designed for use with aggressive e-juices.

Made in Germany by Svoe Mesto. Requires the Kayfun Lite 2019 to function, sold separately.
