The UNi-PRO You Can Do It Brushes are synthetic interior/exterior paint brushes with solid, round tapered filaments. These economical brushes are perfect for creating a silky smooth finish and come in a variety of sizes to suit every application. Handy tip:If you are painting overnight, make sure you wrap up your paint brushes and rollers in cling wrap, so they don’t dry out. They can then be reused the next day to finish off your painting task.
