Zebra Sharbo X ST3 Multi-Function Pen, Black, SB14-BK

This multi-function pen allows you to freely combine refills (choose two ballpoint refills + mechanical pencil diameter, sold separately). This pen features both a mechanical pencil and a ballpoint pen in one, allowing for use with a twist-and-retract mechanism. [Product Features] To encourage creativity, the pen's "shake-in rattle" has been improved from the previous Sharpie model, resulting in increased product rigidity. The operating mechanism is designed to provide a smooth, rotating feel when switching refills. The clip features a springy spring that provides sustained clamping force, making it easy to clip into thick notebooks and other items. The eraser is also included, and a gray eraser is used to prevent smudges from being noticeable after erasing. The knock head is made of resilient elastomer, providing a smooth knock action. [Features] Create your own personalized pen by choosing the body, one mechanical mechanism, and two ballpoint pen refills. (Note: Body only; ballpoint pen refills and mechanical mechanism are not included.)
