For shoe care. This is a set of a shampoo stick and brush to remove dirt from shoes without water. I bought this after being recommended it by a shop staff member when I purchased white sneakers. I have used it 2-3 times. There is a feeling of use, so please refrain from purchasing if you are concerned. *From the introduction site: ・A reliable friend for caring for white shoes! "SHANPOO STICK" for removing dirt. It seems like you can clean it up immediately when you notice dirt. Thank you for looking.
