Utrecht finest sablette one stroke brushes are handmade with long-lasting "Golden" nylon hairs. They have the feel of red sable. I have used this brush for several years. They are very versatile and durable. They are double crimped, easy to clean, and most importantly, they are priced right. I have used these brushes on almost all of my paintings from start to finish. You can use them wet for a smooth finish and you can use them dry for seamless transitioning and blending. I even use them after the painting has dried to apply damar varnish to the painting for extra dimension. I highly recommend this product. Thanks Utrecht.
