Brand: Pentel Color: Gray The "Orenz AT" is a mechanical pencil equipped with an "automatic lead advance mechanism" that automatically feeds lead until it runs out with a single click. The "Orenz System," which protects the lead with a pipe, allows you to write for extended periods without breaking even the finest lead. It features a low center of gravity design and a grip that combines metal and rubber, providing both ease of grip and stable writing feel. This is a brand new item that has never been used since purchase, and the eraser is also clean.
