Bikou Kobunboku is a more subtle version of the traditional Ko-bun-boku formula. Very soft and fresh, with just a hint of cassia and other chinese herbs, and containing both fine Sandalwood and Aloeswood. The Bikou #125 (green box) and the #205 (red box) have the same scent, but the #205 Bikou is the Smokeless Version (produces no smoke). However, the #125 Bikou produces Less Smoke than most other incense. They are both a beautiful, calming scent.
