Seed Sand Eraser 512
SEED is considered to be one of the first manufacturers of erasers in Japan. After the Second World War, the price of natural materials such as rubber was so high that SEED decided to develop erasers made of plastic and finally patented the product in 1955, ahead of all other manufacturers. A major advantage of plastic erasers is that they do not age and dry out like erasers made of natural rubber. The 512 was specially developed for erasing ballpoint ink.
