Vintage La Regale handmade sequin clutch

I believe this to be 1950s but I am not 100% certain on its age. I have determined it is definitely prior to 1984, though. It is in amazing condition. I don’t believe there are any sequins missing, the inside is spotless. The only thing I’ve noticed wrong with it is some age related discoloration on the zipper. This comes with its original box! Handmade in Japan.
