Prior to Japan's industrialization, cotton bags permeated with persimmon tannin or kaki shibu were used in the production of sake. Crude sake, or sake lees, filled this sakabukuro (sake bag/pocket), and under pressure, filtered sake was forced out.  Used countless times, these handsewn bags required mending, and their eccentric stitches and patching are evidence of its hard life.

Sakabukuro, especially the mended variety, are collectible in Japan and abroad.
