Radar 60th Anniversary Rainbow Eraser Set
Without discussion, these are the best erasers we know - and now the most pleasing. For eraser lovers - here are 50 small erasers, each one in its own coloured sleeve made in celebration of 60 years since Seed released its best selling, and the world's first plastic eraser in 1968.
After WWI caused the usual importation to Japan of German stationery goods to cease, the Japanese industry, then growing rapidly, begun production of goods such as pencils and erasers for its quick growing domestic market due to the recently introduced compulsory eduction reform by the Meiji government in 1900.
Established in Osaka in 1915, Seed Ltd, then called Miki Yasushi-saku rubber manufacturing plant corporation was among the very first companies to manufacture Japanese erasers. Noticing that the fluctuating price and quality of natural rubber impacted their finished product, the company begun developing erasers made of soft vinyl chloride - first patented and by Seed in 1955 ahead of all other manufacturers.
A major advantage of plastic erasers was that these did not age and dry out as natural rubber ones do. The former did nevertheless continue to dominate the market regardless and plastic erasers only really came to be used en masse in the late 60s.
This set contains 50 erasers, each measuring 43 x 18 x 12 mm
