This is beautiful nice and thin slim perfect brush bristles no shedding of the bristles ruining the paint work and my cutting in looks like a pro did my walls this is the best brush i have ever come across and worth every penny keep your hand very steady and try not to hesitate when cutting in just move along with the flow but very slowly pull away from the line as opposed to pushing against it pushing against it will only make it bleed into the joing paintwall pulling away allows it to bleed onto the line perfectly
