Built for oil and acrylic painters who demand performance and versatility, the hog bristle filbert from Rosemary & Co features natural, flagged hog hairs that carry rich paint loads while maintaining resilient shape and spring. The oval-end filbert allows broad sweeps and soft blending across backgrounds, yet when held on edge it creates refined lines and transitions. Finished on a raw-wood handle, this economical yet high-quality brush is ideal for both professional studio work and serious student practice.
