This Tiny Hokkaido roller 'Dots' and a visible mold line. 

These 'dots' appear to be vent holes in the molds used to create rollers.  Typically, the glassblower would twist the newly formed roller as the last step before removing it from the mold.  For whatever reason, that step wasn't done on this particular float.  Seven mold 'Dots' are clearly visible on this roller.  There's a smudge of glass that may have obscured a would-be eighth dot.

It measures 5 1/4 inches in length.

This undocumented mark appears to be 'Maru Yoi' 良.  The stamp is deep and clear ... with all the points of the mark showing.

I really like marks that are deeply pressed into the glass.  These deep marks are typically found applied near the edge of the seal.  This mark is about 1 1/4 inches wide or a little bit bigger than a quarter.

One aspects that draws me to this kind of stamp is how far the Yoi 良 symbol is raised up above the surface of the glass.  They are so bold and clear ... it's easy to see them, even from a distance.

This is an extremely rare float with only 3 examples of this mark that are known in collections.

I won this float in an epic battle on eBay.  It was an expensive purchase for sure but I figured it might be a long time until I'd ever have a chance to buy another Maru Yoi float.

I saw this float when a friend of mine visited the Hokuyo Glass Factory in Japan.  This pure black glass float was sitting in the background in some photos that they had taken inside the Hokuyo gift shop after they toured the glass factory.  I asked them about this float and they told me they could purchase it on my behalf the next time they went there.  Shortly before they left Japan they were able to make another trip back to Hokuyo and purchase this float.

It's a tank of a float.  It's very heavy for its size.
