This ultra rare Japanese glass float is known among collectors as "Buddha Head" according to it's unusual texture: it has amazing tubercles on the surface.

I know about existence only three Buddha head floats. I found mine on one of the Kunashir island's beaches (Russia). The 2d float from collection of one Japanese collector was picked up in Fukui (Japan), it has the same color and size as mine. The 3d Buddha Head "lives" in the USA, it's a bit bigger than mine and has blue-green color.

There are three marks on my float. The characters are well stamped. The mark on the seal button is "Naka", it means "Center". The 1st side mark is "Saito-siki", it means "Saito style". The 2d side mark is "Tokkyo", it means "Patent".
