Opened for photography. Bamboo charcoal, size 19cm, product of Nakagawa Masashichi Shoten Co., Ltd. Uses: Muddler: The bamboo charcoal makes water taste better. It has porous properties that make beer foam creamier. Shoe deodorizer: It effectively absorbs dirt and odors, providing deodorizing and dehumidifying effects. Room deodorizer: Moderate airflow generates strong negative ions. The negative ion effect not only purifies the air but also promotes relaxation and comfort. If it gets dusty, the effect diminishes, so wash it with water and dry it in the shade. Price negotiation not accepted.
