Approximately 1.3 kilograms remaining. Our household's strong ally, "Pikattoron," has arrived!!! For our house, which has a continuous flow from the dining room to the kitchen to the living room, drainage odors are a major enemy. I usually pay attention to cleaning the drains, but sometimes I end up slacking off... I found this online and tried it, and I was amazed by its power!! I regularly use it in all the drains in the house.
