This is a brand new Road Runner case designed for a resonator banjo of roughly 13" diameter. The internal length is 42" overall, with an internal depth of about 4.5" (give or take some squish from the foam, bridge height, etc.). This is your chance to grab a very affordable, durable case for your resonator for a great bargain! The only noticeable wear are a few minor scuffs on the exterior; case strap and keys never used and are included in the pocket. We cannot guarantee the fitment of your instrument, so please take measurements before purchasing, as we will need to charge a restocking fee for any returns.
