This is Bonstar's "Steel Wool Pound Roll." Only a small amount has been used. Please check the second photo. It is an iron abrasive, suitable for polishing and cleaning metals, floors, etc. It is manufactured without using oil, so it can be used with detergents and industrial oils. Because it rusts easily, it is recommended to dispose of it after use or dry it thoroughly. It cannot be used on fluororesin-processed products such as Teflon, glass, plastic, aluminum, or wood. Reference price: 1980 yen per roll
