Care Guide
This is an official case for Koss Portapro.
I own multiple of these and this one is unopened.
I am selling it as I am organizing my belongings.
As this item is an awkward size,
it will be shipped using Yu-Packet Plus from Japan Post.
This listing will end on 3/29.
On 3/30, I will take it to an audio buyer in Tokyo along with other items.

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.
