Royal Writing: Old Man and Old Woman Clam Matching These are clam shell crafts. Clam matching (kai-awase) is a Japanese game that has been played since the Heian period. They are also valued as tea ceremony incense containers and tea utensils. I think they would also be good as interior decorations, collectibles, or ornaments. "Old Man and Old Woman" are symbols of marital harmony and a happy marriage, and are often used as decorations for betrothals and weddings. They also symbolize longevity, representing the couple growing old together until their hair turns white, and are familiar for celebrations of longevity such as the 60th and 70th birthdays. Please use them as a gift. They have been carefully stored in a box for many years, but the box has stains due to aging, so I will sell them without the box. If you still want the box, please contact me and I will include it.
