Bristle preserving paintbrush cover

A paintbrush cover comprising:

• a unitary body enclosing an interior space perforated by an inlet and an outlet, the unitary body including
• a front sidewall,
• a rear sidewall,
• a right edge, and
• a left edge,
• wherein the front sidewall, the rear sidewall, the right edge, and the left edge from a substantially rectangular structure enclosing the interior space;
• at least two projections advancing inwardly into the interior space, such that when a paintbrush is inserted into the interior space, the projections press against the paintbrush and resist withdrawal of the paintbrush from the interior space;
• wherein the unitary body is inwardly tapered towards the inlet;
• wherein the front sidewall and the rear sidewall each inwardly taper towards the inlet;
• wherein the front sidewall is perforated by an aperture, the aperture being at least one quarter of an inch in diameter;
• wherein each of the right edge and the left edge are perforated by at least one vent;
• wherein each of the at least two projections bridge the front sidewall to the rear sidewall;
• wherein the unitary body is sufficiently elastic such that a paintbrush having a handle, bristles, and a ferrule may be inserted handle first into the inlet, such that the bristles and the ferrule are contained within the interior space, and the handle projects outwardly from the outlet, and such that the brush may be withdrawn out of the outlet;
• wherein the outlet is narrower than the distance between the right edge and the left edge;
• and
• wherein the inlet extends between the right edge and the left edge.
