Simply take one paper, fold into an accordion shape and light one end, then, blow out flame. You will see that the paper reacts like incense and because of the accordion fold you should be able to stand it on its side
20 papers per box.
After folding accordion style, light just a corner and blow out the flame. The ember will travel across the entire paper over a few minutes and will release all of the fragrance.
Always place on a glass or ceramic surface (Plate or bowl) to burn.
