In simple terms, Hong Kong agarwood is agarwood produced by the Aquilaria sinensis tree (also known as the "Guanxiang tree") of the Thymelaeaceae family under specific conditions. Formation: This resin interacts with fungi and wood tissue over a long period, accumulating and solidifying. After several years, decades, or even over a century, the final product is a black or dark brown part, rich in oil, with a strong fragrance – this is "agarwood."

It is a representative of high-quality "Guanxiang" agarwood. Size: Agarwood bead: 8.4mm Inner diameter: 16.5cm, stretches with elastic.
