Rokuzan Ceramic Obi Clasp, Obi Accessory, Antique

Thank you for looking.

This is a ceramic obi clasp that I found while organizing my parents' home.
It says Rokuzan on the back.
It is an antique that has been used, and I don't fully understand its value, but I am listing it in hopes that it can be passed on to someone who does.
I apologize, but please judge from the photos, and refrain from purchasing if you have any concerns, however small.

It will be carefully wrapped in bubble wrap and sent via YuYu Mercari便 or RakuRaku Mercari便.

I would be delighted if those who love kimonos or are collectors would be interested. Thank you very much.
