These masks are made from lightweight cotton shibori hand dyed in natural indigo that we picked up from a local artisan on our last trip to Kyoto. Sadly we only brought back some small pieces so there’s only a few masks available. Mask is double layered and has a third open layer to accommodate a filter such us a PM2.5. Pattern placement and liner color may vary. Comes with nose wire and small size adjusters that can be easily removed for XL sizing. Machine wash cold, tumble dry low. Filter not included.
