This is a traditional sakabukuro, a sake straining bag, dyed with persimmon tannin (kakishibu).
Sakabukuro were made from thick hemp or ramie cloth and used repeatedly in the sake-making process, where their utilitarian purpose created a distinctive texture and patina over time.
　
Persimmon tannin provided natural waterproofing, antibacterial, and preservative properties, making it an ideal dye for brewing environments.
This piece shows deep, warm brown tones from long-term use, along with a soft yet robust texture developed through repeated washing and handling.
　
One section bears a visible patch reinforced with simple sashiko stitching, revealing how it was carefully mended to prolong its life.
Originally a purely functional brewing tool, it now holds a quiet beauty that makes it a striking element for interior styling or display.
