Inside each pouch you will find a single use botanically infused Spacemask.
 
The heating process works by a thin layer of iron filings entwining with the oxygen molecules in the air. 
 
The ever so relaxing botanicals is in a low concentration.
So you can enjoy its fragrance without irritating the skin.
 
Now just place the Spacemask over your eyes and the loops over your ears.
Recline and enjoy.
