This is a DIY char cloth kit that can be reused over and over again.
 
  Comes with a 4” round tin with a predrilled cover to let the smoke out.  Eventually the smoke will exit the tin thru the hole and become a flame. In a safe way remove the tin from the fire when the flame gets to be about ½” high and place upside down on a safe cool flat surface. Don’t open the tin if it is still warm.
 
Kit contains
4” diameter reusable tin
8 pieces of 8-ounce weight 100% cotton denim
Directions
4 ply thick reusable zip-lock bag for storage
1 precooked charred cloth piece
