Cheap Vintage Beaded Envelope Bag

I have no idea how old this little BonSoir gem is? It could be from any decade 1900 going forward, but if I had to guess, I would say the 1980's. Then again it could be the 1920's. I'm no help, and I'm the one selling it. It's a pretty sleek little bag cheap, in excellent condition. It's sexy, and conservative at the same time and will be a nice addition to any outfit. Tag reads, hand made in Japan with Italian beads.
