Nag Champa by K. Hall has a very heavy, earthy, grungy scent. Nag Champa is the original incense fragrance, so when many people ask generically for "incense", they are looking for this scent. Nag Champa by K. Hall is available in a 100% vegetable wax candle that lasts 60 hours and burns very cleanly and fragrantly. The K. Hall Nag Champa diffuser comes complete with vase, 8oz of fragrance oil and absorbant reeds and lasts approximately 6 months. K. Hall also offers an 8oz refill bottle of fragrance oil.
