T450.  Iron sukashi tsuba.  7.7 x 7.7 x .5 cm.  The nakago hitsu-ana is .7 x 2.5 cm.  The rim is bamboo and I see what may be tea wisks and ginger; the rest you’ll have to figure out.  Both ryo-hitsu have shakudo pillows: nice touch.  The tsuba is very well made and condition is 1st class: there is a lot to like here.  $275.
