You are looking at a custom made Elegant Sierra Pen Chrome & Sat Chrome Twist Pen. The wood/acrylic parts are turned by myself in my shop, and the pen is assembled from a kit. This one is made with an acrylic blank in Turquoise pattern. Very unique looking pen. The pen operates open and closed by twisting the rear section. As with all my products the one in the photo is the one you will receive. Pen uses Parker style refills.
As with all products colors may very from computer to computer, so the photo may not be the exact color of the piece.
