Regarded as the purest, most effective type of activated charcoal, Binchotan sticks have been used in Japan for centuries to filter and purify water. Add one glass-like piece to a carafe of tap water to absorb unwanted toxins and impurities as well as improve the taste. Each stick can be used for up to three months.
Made with 100% ubame oak, a tree native to Wakayama, Japan. Unlike plastic filters, charcoal is entirely biodegradable and can even benefit your garden.
Contains 1/2 pound of charcoal.
Can be disposed of in soil once they start to diminish (about 3 months)
