Balance Natural Ash White Incense Burner Ash Tenku Ash Diatomaceous Earth Ash Set of 4 Bags + 1 Bag with More Than Half Remaining. This was purchased online and is a top-selling product on Rakuten, so I believe it's a good quality item, but I'm selling it because I bought other incense burner ash. It has high heat retention, and almost no incense remains unburned. It's not too light, but substantial, so the incense stands up well, the ash doesn't scatter easily, and it doesn't clump. This incense burner ash is safe and reliable, made using only domestic diatomaceous earth. The "fluffy and substantial" texture is achieved by high-temperature firing of diatomaceous earth with a moderate particle size (not too small, not too large). It has high heat retention, and almost no incense remains unburned. (Incense often burns completely to the end, but there may be some residue when inserted to the bottom of a deep incense burner.) A generous set of 200g x 4 bags. (I'm including 1 bag with more than half remaining, so a total of 5 bags) 3-sun (approx. 9cm diameter) incense burner: approx. 3 uses / 1 bag 3.5-sun (approx. 10.5cm) incense burner: approx. 2 uses / 1 bag 4-sun (approx. 12cm) incense burner: approx. 1 use / 1 bag 4.5-sun (13.5cm) incense burner: 1-2 bags needed The packaging has a zip closure for convenient storage.
