Model number: SBS35-RC SB Sand Beige Sharbo Nu Used 2-3 times. In beautiful condition. 4 colors: red, blue, black, and mechanical pencil. [Product Description] Unique mechanism centered around the mechanical pencil. Easy to refill mechanical pencil lead from the top. One pen with black and red ballpoint pens and a mechanical pencil. The ballpoint pens use Zebra's original emulsion ink, which writes richly and smoothly. The mechanical pencil allows you to refill the lead from the top by housing the mechanical pencil mechanism in the center of the body while incorporating two colors of ballpoint pens into one pen (patent pending). In addition, the lead flex is small, providing a stable writing feel. Rotating the shaft changes the color of the sign in the window under the clip, indicating the function in use.
