This is a shakuhachi. I believe it is quite old.
I am not an expert, but it is inscribed with Shunyo.
The embouchure is chipped and requires repair.
There is also a dark stain-like mark near the bottom, so please check the photos.
Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.
Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.
Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.
Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
I’ve been using the product for a while now and it continues to work well. Everything functions as intended and I haven’t noticed any problems.
