I am selling this item because it is no longer needed after cleaning out my parents' house. I have used it about twice, but there are no noticeable stains. The protective seal on the switch is still attached. This is a cooking appliance that adjusts the temperature of sake to keep it at its optimal drinking temperature. - Model: NBE-1 - Brand: meets - Accessories: Sake vessel, cup, plate - Functions: Temperature adjustment for atsukan (hot sake), joukan (warm sake), and nurukan (lukewarm sake) - Usage: Sake temperature management Thank you for looking.
