These are all very cheap Otsuka tosai but are they Kage Shiro Utsuri or Matsukawabake? All of them have blue skin which I've never seen on Shiro Utsuri, but have seen on Matsukawabake/Kumonryu tosai. However the sumi looks like it's wrapping around the body, rather than a lateral pattern. I also see some with Asagi hi around the belly, but have seen "Bake" with secondary coloration as well...
I'm in love with the Kage Shiro but will the Asagi reticulation come out later on these, even though it's not evident currently? Or should I just wait until I see something better?lol
