An electric coffee grinder with a switch that allows you to adjust the grind size. You can easily achieve your preferred grind by simply pressing a button. Originally priced around 10,000 yen. Used about 10 times and cleaned at home. Selling because I received another one as a gift. I've taken good care of it, but as you can see in the photos, there are some areas where beans seem to have gotten in. The warranty has expired, but I still have the instruction manual.
