SEED is considered one of the first manufacturers of erasers in Japan. After World War II, the price of natural materials such as rubber was so high that SEED decided to develop plastic erasers and eventually patented the product in 1955, ahead of all other manufacturers. A significant advantage of plastic erasers is that they do not age and dry out like erasers made of natural rubber. The "Radar" was launched in 1968 and is considered one of the best-selling erasers in Japan. Recommended for clean, soft erasing. One of the most powerful erasers ever. (Model SEED EP-SN Sun)
