These highly rare, Japanese fishing floats are historic and beautiful. They are what we call "rolling pin" floats or "rollers" as they look like the shape of a kitchen rolling pin.
At one time these were attached to the fishermen's nets to give the nets buoyancy. Each been hand picked from coastal, Pacific locales and show their original color, bubbles and some frosting from exposure to the elements of the ocean.
They each measure right about 5" across. Each is a beachy shade of greenish blue teal color and each show glass blowing bubbles and the end "button". US dime in photo for sizing reference.
