Our Bon Bon Smelters are similar to a popular women's fragrance. Bon Bon is a vibrant creation of mandarin and orange slices, crystallized with caramel and juicy fruit. Method of Use: - Place a number of Smelters in a burner (depending on the size of the burner) - Light a tea light (approximately 4 hours) and put it in the burner - Let the scent spread in the room Smelters last 2 to 3 tea lights. Each bag contains approximately 20 pieces Strengths: We choose to produce Smelters in 2 strengths (mild and strong). Conscious! Because not every room is the same size and every person has a different need. So it is highly recommended to include both strengths in your range.
