Very nice dark blue seal on a 3 inch Japanese glass fishing float. 

The frequency of Blue Dots on 3 inch size floats is relatively low.  There seems to be more blue dots on 2 inch and 4 inch floats than on 3 inch floats. 

The blue seal button is a particularly nice dark cobalt blue color, too.

This float has net pattern frosting over the entire float.

This float has excellent provenance. It was beachcombed in the Aleutian Islands by Paul Umlauf.
