COGIT Foaming Laundry Soap Case By putting a UtaMaro solid soap bar in this case and adding water from the top, the brush creates foam, allowing you to remove dirt without getting your hands dirty. I was able to use it by putting in a few small pieces of UtaMaro soap, and it still foamed up. This is a slim, vertical type. The vertical type is recommended for pre-washing collars and sleeves. I bought it as part of a set, but it seems like it will last a long time, so would anyone who needs it like to have it? The minor scratches on the outer plastic packaging were originally there. Thank you for your understanding. The following is a copy from the purchase site: Foams up firmly just by rolling it around! A convenient laundry soap for removing stains from clothes. However, many people may find it difficult to use, such as where to put the soap and how the soap doesn't dry easily. For those people! An item that makes laundry more convenient and fun is here! This "Foaming Laundry Soap Case" has a spring-loaded lid that presses the soap against the brush at the bottom to create a good lather, so you can remove dirt from clothes, etc., while the soap is still in the case. The spring-loaded lid allows you to use even small pieces of soap without waste! The brush also rolls around, making it easy to wash! After use, the lid has air vents, so it dries easily, and the soap, which used to be a problem to place during washing, can be placed on the tray without getting the surroundings dirty even if it's wet. #Foaming Laundry Soap Case #CleaningConvenienceGoods
