This is a Mitsubishi Pencil Uni Holder B MH500B. Over 30 years ago, I submitted an illustration to "Pro Baseball News," a program that aired on Fuji TV, and it was selected. I received a Uni Holder as a prize. The "Pro Baseball News" logo on the body is printed, not a sticker. There is no box. Due to long-term storage, the body has scratches and dirt. There is some discoloration on the metal part of the core holder. Also, there are spots, possibly rust, on the front and back of the clip. There is a small crack in the knock part. I checked if it can be used for drawing. It draws smoothly. However, I don't know the hardness of the lead. The core holder, unlike a typical "lead advances a fixed amount with each click" mechanical pencil, uses a mechanism where the lead stored in the shaft "falls by its own weight." You adjust the lead to the right length using its weight and use it while sharpening the lead. The lead has a "stopper" to prevent it from falling out when clicked.
