Since colors and shapes are similar to domestic manufacturer products (Nikkyo Dai X 03), purchase for confirmation. Check the package and make it in China. I checked it with the Nikkyo Dia Agent in Japan and it was a copy product. Especially not written as being made in Japan, but the country of origin China. Shape and color should be written as copies of Nikkyo Dai. == Although it seems that there is no place where the function is inferior especially at the stage of trial cutting, oil leaks etc. occurred. There are also advantages (cheap) in terms of price, so I think that it is better to sell it by specifying it as a copy made in China made domestically.
