It is a refill type of disinfectant and deodorant spray. It is very convenient to refill it in your favorite container and place it in each room, or put it in a small container and carry it around when you go out. If there are many people coming and going, such as commercial facilities, public institutions, hospitals, nursing homes, etc., this is highly recommended in terms of cost. * When refilling, please refrain from transparent containers as much as possible.
