This is an antibacterial, dishwasher-safe trio set, One Piece 24 (One Piece, dishwasher-safe cutlery set, chopsticks, AG silver, antibacterial, made in Japan) set. I bought this for my son's入学 (nyuugaku - entrance to school) at his request, but I accidentally ordered two and couldn't return one because the return shipping and fees were too high... Unused and unopened.
