A unique set of pencil sharpeners with insect designs. - Product Name: NIKKEN Insect Sharpeners - Features: Pencil sharpeners shaped like insects. I think these are rare items, probably not many left. They were sold for 50 yen each in the Showa 40s-50s (1965-1984). There are some scratches and dirt, but for some reason, they haven't deteriorated much, and it's strange how fresh they look.
