Abstract: The present invention is an improved paint brush which can be attached to the perimeter portion of a paint can opening such that the bristles of the brush are oriented into the paint can at an angle of between 0° and 90° from the vertical. The perimeter of this paint can has an upwardly extending rim having upper and lower ends, while the paint brush has a mid portion connecting a handle to a set of bristles. A notch is provided on a side of the mid portion between the handle and the set of bristles for attaching the brush to the arc of the can, the notch defined by an upper lip oriented towards the handle, a lower lip oriented towards the set of bristles and an opening separating the upper and lower lips.
