Antique Asian Korean Korea Choson SILVER NAPKIN RING

  

Antique Asian Korean Korea Choson SILVER NAPKIN RING. Old Asian Korean Silver Napkin Ring. These letters widely used in various items like tobacco box, blue and white pottery, rice bowl, other decorative arts for royal society peoples. I believe this one is from old Korea, late choson dynasty because silver content is lower than western sterling silver(92.5 %).

Could be used in hotels like SONTAAK Hotel (????????) or other three hotels in Inchon(?????
