Conventional channel brushes have disadvantage of having limited amount of filaments you can include. Filaments are also in rows, even if the job could be done with the most outer circle of the brush. In TURBOLINE® system the bundled filaments are actually in the furthest circle. Best flicking action is gained when only the tips of the bristles are lightly touching the surface. In TURBOLINE® tufts the filaments also support each other. It results that the brush pressure can be minimized which increases radically the lifetime of the brush.
