This mark is similar to WP #125 Sa サ Shi シ except there is a line above the shi symbol.  So, this mark could be called Sa サ Shi シ Ichi 一.

The float measures about 3 inches in diameter.  It's also almost completely frosted.

This 'Dot Roller' is a Hokkaido roller featuring 6 distinctive raised dots. There are 3 dots on each side of the float.  The barrel has 2 dots and each of the ears has 2 dots.

These dots may have occured as a result of holes in the mold.

There is also a very pronounced mold line where the two halves of the mold met.

This float has WP #25 'Dai' 大 stamped on the seal.  It seems reasonable to assume that Daiichi Glass Company was the float maker.

There's a very nice molded texture on the surface of the glass, too.

This float has a very unique seal.  One feature that makes it unique is that it's a double seal.  The inner seal appears to be made of brown glass.  The thick outer seal is made of clear colored glass.

The glass in the body of the float is quite thick for a float this size; plus there are tons of bubbles.

This is an authentic Japanese glass fishing float.
