The Kuro Cube purifies and freshens the air of any small space, be it a closet, a refrigerator.

Made from powdered and compressed White Charcoal, it adsorbs gases, pollutants and odors from the air, without the use of chemicals or perfume.

PROCESS: First, ubame oak is baked at low temperatures in a handmade clay kiln. The temperature is then rapidly increased before the embers are starved of oxygen by shutting the opening to the firebox, thereby preserving the carbon content of the wood.It’s that last step that differs from typical charcoal making, allowing Binchotan to retain around 97% of its carbon content. Once used, each charcoal product goes back to nature as a rich fertilizer.Kishu Binchotan remains the finest, densest and purest form and is hand-made through a slow process over six weeks. This process is passed down through generations and the ritual around it is cherished greatly.

PROPERTIES: For centuries, White Charcoal has been known for its purifying, enriching and restorative properties. Filled with countless microcavities, the surface area of just one gram of the material equals 250 m2, around the size of a tennis court.This allows White Charcoal to absorb impurities from water, air or even skin, while releasing vital minerals absorbed by the living tree, such as potassium, magnesium, calcium and phosphorus.With that, White Charcoal can turn tap water into pure mineral water, remove odors from the air, and work as a balancing agent for the body through the flood of negative ions it emits.Despite the intensity of the activity taking place within White Charcoal, its surface is hard and beautiful; like a piece of porcelain.
