UNi-PRO three piece brush set can be used for all painting jobs, at home or at work. These square brushes have synthetic bristles with contoured wooden handles for easy gripping. Each set includes 25mm, 50mm and 75mm brushes. 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.
