Tokyo Old-Established Showa Supreme Oil Smoke Ink One and a half blocks, rare ink, with a chip! I understand this is a high-grade oil smoke ink from a now-defunct, old-established Showa-era Tokyo shop. I was told by my grandmother that it was pure rapeseed oil smoke ink, received from a friend. It's over 50 years old, so please understand that there are some chips and scratches. This is a rare ink, only one block available. If you are interested, please inquire early! 10-46
