【Rare Vintage Item】 This is a top-grade ink, "Tessaiō Shoga Hōboku (101 Oil Smoke)," from the prestigious Chinese ink manufacturer, Hu Kaiwen Ink Factory. This is an extremely valuable "old ink" confirmed to be manufactured in 1980 by the inspection stamp on the bottom of the box. Chinese inks from the early 1980s are highly prized by calligraphers as "golden age inks" due to the exceptionally high quality of their raw materials. ■ Product Features Brand Name: Tessaiō Shoga Hōboku Rank: 101 (Top Grade) Manufacturer: Hu Kaiwen Ink Factory, Anhui, China Year of Manufacture: 1980 (Box has an "80" stamp) Type: Oil-based ink (uses the highest quality soot) ■ Condition Unused, stored item.
