Old Chinese glass floating balls

Product Details: These are original glass fishing balls once used by Chinese fishermen to keep their nets or drop lines afloat.

The balls were made from recycled sake bottles, resulting in air bubbles and a greenish color.

blue and green hues, with occasional brown colors. The glass balls are still able to float, making them great decorations in water.
