Question 1

there were no directions in my set.  It is liquid.  I thought I rub the coin and it activates? not happening

Accepted Answer

The coin is the key but you do not rub it.  It is not really flat but bends out at the edges.  To activate the gel to heat, simply bend the coin shaped object so that bend goes the other way.  Convex to concave.  After use, to reactivate it simply immerse it in boiling water for 10-20 minutes.  It helps to put a wire rack or something in the bottom of the pot so that the gel pad does not rest on the bottom of the hot pan while boiling.  When the gel turns completely clear again (versus cloudy as it does as it cools off during use), it is then ready to use again.  I hope this helps.

Question 2

the coins in 5 of my packs are extremely stiff.  so stiff in fact that I cannot activate the pouches.  What can I do?

Accepted Answer

Bending the disc starts an exothermic crystallization of the gel (i.e. it goes opaque and gets hot). And when it loses its warmth, all you have to do is wrap it in a towel and place it into boiling water for about 5 minutes and it resets itself (the crystals completely liquefy). Once it cools off from its boiling bath, it is ready to be used again.

Question 3

What size are these?

Accepted Answer

4" x 2 1/2" about, they are probably their hand warmer style but are great if u travel. Or want to throw one in your purse. I got them for my lower back and even tho they are small they work great.

Question 4

Can they be warmed up in the microwave?

Accepted Answer

No. You pop the metal coin that resides within the pack. Then to reset them you boil water and hold them in with some tongs until it returns how it was prior to use.
