I'm currently cleaning up my parents' house. I'm not entirely sure how these nails are used, but they were among my grandmother's belongings, who used to enjoy tea, so I believe they were prepared for use in a tea room. If anyone is looking for them, would you be interested? The tatami tray in the photo is not included in the sale. Also, please refrain from inquiries about selling individual items.
