I understand this was purchased for cleaning the bottom of a kama (tea kettle), but I'm told it has never been used. It also has a string attached for hanging. This is a scrubbing brush for removing soot from the outside of the kama's bottom. #ChagamaArai (Tea Kettle Cleaning) #Shuro (Palm Fiber) #Tawashi (Scrubbing Brush) #MizuyaYouhin (Water Room Supplies) #Chadogu (Tea Utensils) Size: Length 16.5cm, Diameter 5.0cm
