We started selling very valuable old paper made from a special mixture of soil.
According to a manager of Kobaien headquarters, one day in autumn 2021, he found some interesting wrapping papers which covered about 200 years ( Edo period ) old ink stick in their storage.
He had never seen a paper like that so he brought it to a laboratory in a university. The professor there then suggested that he should go and meet an old traditional paper manufacturer in some place in the Kansai region.
He went there. Then the grandson of the paper manufacturer family showed him this special paper in their old storage, which now they have lost the manufacturing method. He sent the paper sample to a professional calligrapher who liked it very much and made some good calligraphy artworks.
This paper is one of the only ones sold exclusively in the world by Kobaien. It is very suitable for calligraphy.
