Excellent 1940's Occupied Japan Sewing Box Kit Thimble Mirror Thread Pincushion

I’m searching online and I don’t see any of these in the same condition as mine. Occupied in Japan sewing kit. Plum colored velvet top, inside - none of the thread has been used and the thimble is in excellent shape. Not sure of the type of metal, but it is silver colored. Mirror has some discoloration from age.
