Japanese Style [Chirimen Tsumami Zaiku] Keychain - Handmade, with Bonus Brooch

I received this a long time ago from a kumihimo artist, but I couldn't bring myself to use it because it felt too precious.
I would be happy if someone could use it.
Both the front and back are beautiful.

As a bonus, a handmade brooch is included (made by a different person - please let me know if you do not want it).
