In order to enjoy the slow change of equipment, we recommend the following before you use for the first time after purchasing a vessel. (Filling) Immerse new equipment in rice sharpening juice (or rice bran with water) and boil for several minutes to several tens of minutes. Wait as it is until it cools, please wash and dry thoroughly before use.

Even when you are usually using it, we recommend that you wear the instrument once and then use it.
