Abstract
Abstract A brush for application of paint or the like is formed of a handle and an applicator envelope. The applicator envelope is an integral piece without bristles formed of soft spongy material. It is connected to a holding extension which is capable of sliding into the handle by a clamping arrangement, such as inwardly bent lateral extensions of a clamping device secured to the holding member which engage the applicator envelope and are clamped against it by the insertion of the holding member into a pocket in the handle.
