This is a beautifully designed vintage pair of large Baoding massage, health, exercise, stress Chinese Balls. They feature a wonderful brown marble swirl coloring. These balls measure a diameter of 1-5/8 inches. These are large and perfect for stress or massage. They come in the red brass latch box illustrated in the pics. The box measures approximately 4-7/8 inches across by 2-5/8 inches wide by 2-1/4 inches tall. The original label is on the lid and front side panels of the box. It has the company logo and Chinese symbols. The manufacturer is Shouxing Ball Factory in China. They are in excellent condition as illustrated in my pictures.
