Tsushima Nagura purchased from Maxim at JNS. Approximate size 210mm 75mm 50mm, with an approximate grit of 5-8k. This is an excellent stone, very easy to use and very fast, with absolutely NO inclusions. I usually use this stone after a the JNS 1k or after an Aoto. Stone is lapped and ready to go!!! The sides are sealed with Paper and Traditional Cashew Lacquer (I believe).
Asking $185 Including Paypal Fees and Shipping (CONUS)
I also Have the small Cube (45 mm x 45 mm x 45 mm) Tsushima Nagura if anyone is interested- ($50) Including shipping and paypal fees
Ignore the bubbles...they are from where I sprayed water from a bottle on the surface and are not part of the stone.
Thanks for looking,
