How to use?
- Remove gel packs from inside the earmuffs.
- Locate the metal disc inside the gel pack, hold between your thumb and forefinger and bend it gently until it clicks.

- Place the gel packs back inside the ear muffs.
- When gel pack is cold and hard, place in a large pan of boiling water.
