Uncommon Knowledge: One gram of charcoal has nearly the surface area of a tennis court!
That's because charcoal is filled with microscopic cavities - so many, in fact, that they can trap odor-causing chemicals from the air. This specially designed Chikuno Cube uses a honey-comb structure to maximize this power - creating a surprisingly effective air freshener for your refrigerator, closet or other enclosed space.
Can be "recharged" each month by leaving it in the sun for six hours. Reusable for up to a year. Do not use where Chikuno Cube could get wet (i.e. the shower). Made in Kyoto, Japan.
