2 x 2" Arroworthy Flat End Paint Brushes. Arroworthy Rembrandt brushes are made with NYLYN Technology filaments to hold and release more paint, which means they can handle even the most demanding paint jobs with ease while still keeping their shape and cutting a tremendous line. These handcrafted brushes also have a high-temperature resistance so withstand multiple tough washes. The slightly stiffer filament of the Rembrandt is preferred by many professionals and gives excellent control.
