Care Guide
This hot and cold therapy device was previously used by my grandfather.
He used it by removing the cap, filling it with hot water to stimulate the skin, and then filling it with cold water to stimulate the skin, believing it enhanced the body's natural healing abilities.
The temperature of the hot water was around 42°C (107.6°F). The cold water was just cold tap water, so I estimate it was around 0°C (32°F).
Please note that this item is intended for purchase only by those who have prior experience using such devices. As this is a used item, there are scratches and stains, but we ask for your understanding.

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.
