This is a Japanese-made "Chaffnon Ver.III" designed to remove chaff and fine particles from ground coffee. It was sold by Sanyo Sangyo, known for the CAFEC brand, as the general distributor. It is said that "by removing chaff and fine particles, which are the cause of off-flavors in coffee, you can achieve a clearer taste and enjoy delicious coffee even more." I used it about twice after purchasing it, and then it was left in the closet, so I'm selling it to declutter. There are no operational issues, but there is some slight dullness on the metal parts of the main body and the glass cup, so those seeking a condition like new should avoid this. The filter part for separating chaff and fine particles has been replaced with a new one by contacting the manufacturer. Only the filter is sold as a replacement part, so it can be replaced if necessary, but it is a paid service.
