The cut on the bottom of the glass is a typical Edo Kiriko pattern called "Nanako". As the Nanako part approaches the rim of the glass, the pattern changes and widens. Nanako is a pattern where the cuts intersect without any gaps, and by leaving small gaps between the intersecting cuts, it transitions into another typical Edo Kiriko pattern, the Yarai pattern.
This glass was made by Kobayashi Glass Crafts. It is one of the Edo Kiriko workshops that has been in business for nearly 100 years. Currently, the workshop is run by the third generation, Yoshiro Kobayashi, and the fourth generation, Kohei. This glass was made by the third generation, Yoshiro Kobayashi.
