Showa Retro MATUBA Three-Color, Six-Color Pencils These are old color pencils from the Showa 30s (1955-1964). I was collecting old tools. I found and bought them at a stationery store. Although they are unused, the box has stains, tears, and dirt. They are very old color pencils. I don't know about their quality as color pencils. Please purchase if you understand antique items, old tools, vintage, and antique goods.
