Care Guide
The previous unit of the same model I was using broke down, so I sent it to the manufacturer for repair through a domestic retailer in April 2026. They ended up replacing it with a new unit.
It has not been opened since it was delivered to me.
I have since set up a different environment during the repair period, so I have decided to part with this one unopened.

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.
