Each of them is a series of rather small copper leprechaun bowls, each with a line engraving of plum and other designs on the prospective surface and dots of gallows on the surface, and engraved designs on the inside of the mouth green, which is slightly warped at the edges. A similar piece was excavated from the kiln site of Motoyashiki, so it seems that this type of ware includes pieces fired at Motoyashiki as well as those fired at Oyayaki. However, it is not clear whether they were fired in the climbing kiln at Motoyashiki or the anagama kiln next to it.
