This standard Hokkaido roller is filled with extraordinary amber gold swirls.  

This roller shows signs of quite a bit of use that leads me to believe it is an authentic working. 

There is some shell life attached that appears to be remnants of barnacles.

It also has a nice example of a 'green eye' in the seal button.

Found on Hokkaido Island, Japan.

This is just an absolutely stunning beautiful roller!!!
