Jen Manufacturing Inc. 2 Poly Foam Brush (Pack Of 48) were just what my woodworker spouse and I needed for finishing projects or painting.  The angled head of the 2 brush makes it easy to use in small areas.  The wood handle is about 4 long and  in circumference.  I use these brushes for craft projects or when painting a room in the house to cut-in as necessary.  They work well for getting a smooth finish  no brush marks  when painting a toy or stepstool that we have made for the grandchildren.  Best of all, they are easy to wash and reuse several times.
