Our Topcoat/Varnish brush. is handmade in Sweden and is a very high quality lightweight brush. This tool is mostly made with natural bristles but has a light blend of synthetic bristles to lessen the opportunities for brush strokes. A huge benefit of this brush is that it helps you not apply too much Clear Topcoat Sealer or Clear Finish (which many people do when using a fully synthetic brush). It also works well with any other oil based products or stains. Clean up is easy with soap and water.
