Vintage Original Box Small Balls Japan Ornaments Mercury Glass Feather Tree

Absolutely WONDERFUL set of mercury glass hand-blown ball ornaments in their original box! Set of 12 balls with 3 in each color: gold, silver, red, and blue. The stamp on the side of the box is very faded, but I believe it says Made in Japan. I believe all the balls are original to this boxed set - they look so similar, and they fit the box perfectly. I'm guessing these are from the 1940s or 1950s. The balls are small, meant for a feather tree or something of similar size. Excellent vintage condition. No chips or cracks, although I did not remove the caps to check underneath. Some wear to the paint, which adds to the vintage look. Approximate dimensions: Each ball is about 1" diameter. The box is about 5" x 4" x 1.25". Please check out my other listings - I have many more vintage Christmas items!
