Black polished carbon graphite stick, full-lined ebony frog with Parisian eye, 3-part button with eye, thread/wire grip. Viola 4/4 size. Our new Core Select Bows represent a brand new look in affordable synthetic sticks. The camber is different from any of our other carbon bows, and in our opinion, offers up a beautiful aesthetic compared with any bows in this price range. The fittings and finishing work are also what you would expect from bows in a higher price range.
