Instructions for use:
 

To activate:

Find and grasp the metal disc between thumbs and forefingers. Gently flex the metal disc back and forth until the contents of the heat pack starts crystallising.
 

Twist and squeeze the reusable heat pack until it is completely crystallised. This will soften it and ensure that heat generation is maximised.
 

Place the reusable heat pack in the cover/belt or wrap in a soft towel before applying. (It is possible to apply the heat pack without any cover but exposure to the atmosphere will decrease the warming time.)

 

To recharge:

Once the heat pack has cooled it needs to be recharged. Place the hot pack in boiling water with cloth below, note, prevent the plastic bag from contacting the bottom of the pot for about 5 minutes or until all the crystal is dissolved

 

Note:  

Do not microwave, freeze or puncture the packs. They will not perform effectively and will void the lifetime warranty. Do not ingest contents. If ingested, drink several glasses of water and seek medical attention immediately.
