Nakajima Shigehisa-do TSUNAGO Pencil Sharpener: Connecting Thoughts Includes instruction manual. This is a manual pencil sharpener. You can connect short pencils together to use them until the very end. I was drawn to the concept and used it several times. There are no noticeable large scratches. I cleaned it as much as possible for the listing, but there may still be some pencil shavings remaining. Please only purchase if you understand that this is a home-stored, used item.
