Since it is a replacement cylinder, I prepared it together with the main body. It is a repeat. It is solid and can be applied neatly. Recommended for painting small items. (Translated by machine.)
It is useful as a bond roller for applying bonds to the core material when pasting plywood on flash doors. Since it does not contain as much bond as a hair roller, it needs to be applied many times, but it is easy to clean because it is a sponge. If the sponge becomes hard, you can replace it immediately with this replacement tube, which is helpful. (Translated by machine.)
It is a disposable roller, but if a little force is applied, the sponge around the set screw (nut) will tear off and adhere to the painted surface. It's hard to get them later. (Translated by machine.)
