"Slim Softie" Violin and Viola shoulder pads have been hailed by retailers, teachers and students as the most comfortable and versatile shoulder pad ever made. The Slim Softie can be installed on the violin or viola in seconds and in three different configurations (see photos). Simply slip the elastic bands over the instrument and you are ready to play. Slim Softies are made of lightweight foam, elastic and durable cloth that is completely machine washable and dryer safe.
