Sonora Dendritic Rhyolite cab with the typical mauve and beige interspersed with black dendrites in a muted scenic pattern. Domed top and smooth flat back for bezel setting. This is a very thick cab at 9.21 mm. Size is 43 mm x 34 mm x9.21 mm. A dime is used to reference size. I take all my photos in natural diffused light and do not alter them in any way except for cropping and exposure control to obtain the closest possible to natural color. 100% guarantee of your satisfaction.
