Size: Approx 4 1/4 inches by 11/16 inches. Each lead is approx .4 inches long
A pack of vintage pencil leads from, I would think, the 1930s or 1940s. Each pack has four 4-inch leads in a wooden tray. These will fit any pencil that takes the 1.18mm leads. That includes Yard-O-Led, and many vintage pencils from Parker, Sheaffer, Conway Stewart, Burnham, etc. The pack is in good condition.
