This 4" or grapefruit size float has water trapped inside!
Acquired recently from a collector it is very special.
This happens when the floats, attached to fishing nets, are dragged deep under the sea. The water pressure allows water to seep into tiny cracks in the glass that seal over again once the floats are returned to the surface.
Perfect as a gift for a float enthusiast, or simply to be appreciated as a thing of beauty.
Measures approx: 11cm diameter
