These covers act as a carrying case with an adjustable shoulder strap, a large pocket, and a hand strap. Included on the pocket is a clear business card holder. They are completely padded. We have a 1/2″ foam laminated to a slick nylon to create a lining that will slide easily on your harp. The nylon zipper has our special self-closing back to protect the wood. The water resistant material and the padding will keep your harp well protected!
