Tofu is a pressed mass of soybean fibers that absorbs a large amount of moisture. The fibrous structure ensures high-quality bonding of the granules, forming a dense mass and blocking unpleasant odors, while transforming the energy of the aroma into a mild aroma. The used sand can be thrown into the toilet. The weight of the 100% environmentally friendly 6-liter tofu container is 2.8 kg.
