Kuro-Ushi Sake Masu 4-Piece Set "Kuro-Ushi" is a brand of Japanese sake brewed by Meishu Shuzo in Kainan City, Wakayama Prefecture. This is a home-stored item, so there may be cracks or stains. Please be understanding. Due to high shipping costs, I cannot offer a discount. Kuro-Ushi masu are not often seen even in stores, so I think they are rare. Please consider them if you are interested.
