The ProDec 4" Assorted Mini Roller Set includes ten roller sleeves in three different types, along with a soft grip mini roller frame. It's a useful set for decorating jobs involving different paints and surfaces, without needing to buy separate roller packs. The four medium pile woven rollers are suitable for emulsion paint on smooth and semi-smooth walls and ceilings. Three high-density foam rollers are included for applying gloss and satin paints to smooth surfaces, while the three mohair gloss pile rollers are suited to gloss, satin and woodstains on smooth woodwork. The compact 4" size makes these rollers handy for doors, panels, trim and smaller areas where a full-size roller would be awkward.
