Larger charcoal discs (40mm) come 10 to a package.
Each disc stays ignited for about 45 to 50 minutes. Use
with resins or incense blends that do not contain oxidizers
to promote burning (our own handmade blends are oxidizer
free!). Three Kings brand is imported from Holland, and is
highly recommended by DragonMarsh. (Large size is the
top package in the picture.)
