Yumi Katsura bowl, tray, chopsticks, and chopstick rests (set of 5)

A set of 5 red and black donburi bowls, 5 trays, 5 pairs of chopsticks, and 5 chopstick rests.
These items are new and unused, but have been stored for a long time, so the box has discolored. However, I believe the items themselves are fine.
We ask that you purchase this item with an understanding of this condition.
