Rotring 800 0.5mm mechanical pencil. - Brand: Rotring - Model: 800 - Lead size: 0.5mm - Color: Black Thank you for viewing. I purchased this about three months ago, but I haven't had much opportunity to use it, so I'm putting it up for sale. There is a small scratch on the clip. Please refer to the fourth photo for the extent of the scratch. I will disinfect it before shipping.
