Vintage Mitsubishi Mechanical Pencil Black DEMI-5 Japan With Case 1970s Got this in early to mid 1970s. Includes original styrofoam tray, the pencil, plastic lid, and two containers for additional lead. Some lead in each one. Plus instructions. Case has a “crack” in the lid, shown in pictures. But can’t be felt on the inside or outside. Must’ve bent? Styrofoam tray has a mark on the back side and an area where the extended lead made a notch on the end. Shown in pictures.
