Nakajima Leather Roller for Lithography

I purchased this over 10 years ago with the intention of doing lithography, but I've kept it stored away due to being too busy to get started. It's completely unused and has remained wrapped, so the leather is in good condition. Mr. Nakajima Roller is the only one who makes these now, so you'll likely need to purchase maintenance tools from them.
Please note that there is some dirt on the handle. Returns are also not accepted.
