This is charcoal made by cutting harvested bamboo into strips and steaming them in an iron can. It's a handmade product, so it may not be as good as professionally made charcoal, but it's offered at a lower price. I will send a full box that fits in a "Nekopos" box. Please understand that it may break during shipping. Here are some examples of how to use bamboo charcoal, which I found online: For removing odors in the refrigerator and keeping vegetables fresh: Place about 100 grams in the refrigerator. It eliminates unpleasant odors and keeps vegetables fresh. This seems to be due to the deodorizing effect of bamboo charcoal. For revitalizing plants in flower pots and flower beds: After various uses, dry the charcoal in the sun and reuse it. Crush it into small pieces and mix it with the soil, as it is alkaline and activates the soil. It can be used in refrigerators, shoe cabinets, closets, and rooms to dehumidify and deodorize. It is often used for deodorizing and relaxation in rooms, as an object, or under the floor.
