Kaji Donya 　Bon-zaru (Draining Basket) 　Maru Tray (Round Tray) Set Originally sold separately, I purchased these as a set. Both were used only once for draining water. No oil was used. There are no stains, but there is some water scale? typical of stainless steel on the tray. Purchased online from Nakagawa Masashichi Shoten. Made in Japan Items are sold separately, and price reduction is not possible.
