18mm Evil Eye Cab in Light Olivine. This is a color variation from the normal "Sahara", in that it's all muted metallic Light Olivine green from the top view with light Peridot green, then neutral muted medium steel blue when viewed from the side. The color changes dramatically based on the light and angle that you view the cab by. No hole, but the back is pretty flat, save for the little concave spot where the "iris" of the design is.
