These bags and accessories are made from vintage Obi and Obijime (kimono sash and sash belts). They do not, generally, fold well. They will crease and will not uncrease, no matter how much steam is used.
As such, I DO NOT reccommend washing these items. If they get dirty or a spot on them, spot cleaning is ok, but DO NOT toss the bag in the washer/dryer, and please do not have it dry cleaned.

To spot clean a bag ::

use a paper towel with a little white vinegar + water solution.
1 part vinegar to 2 or 3 parts water is best.
if you don’t like the smell of the vinegar, you can put some orange peels in the solution to make it smell better.
pat the area with the damp paper towel. do not scrub.
do not pour the vinegar + water solution directly onto the bag.
if the area becomes saturated with the solution, use a dry paper towel to pat the area dry as quickly as possible.

vinegar generally won’t discolor the fabric, but it’s always better to be safe, rather than sorry.

These are completely One of a Kind bags and accessories; there will never be exact duplicates.
