Our Peony Smelters have an extremely soft floral scent based on peonies in full bloom. One of the best floral fragrances we've ever had. Method of use: - Place one Easy Block in a burner - Light a tea light (approximately 4 hours) and put it in the burner - Let the scent spread into the room Smelters last 2 to 3 tea lights. Each bag contains 10 Easy Blocks Strengths: We choose to produce Smelters in 2 strengths (mild and strong). Aware! Because not every space is the same size and each person has a different need. It is therefore highly recommended to include both strengths in your range.
