Asano stamped Shiro Mikawa Nagura

A group of 4 Asano stamped Shiro Mikawa Nagura bench stones. These
stones are rare and the supply is fading quickly. I personally bought this group
from the keeper of the Asano stamps on my last visit to Japan. The photos do
not do the stones justice, the whites and the tones are much brighter, and the
228mm long botan is really really long, not just sort of long.
