SofiaMari diatonic accordions feature large pearl buttons, 19 fold bellows with diamond designs, bellow straps with snaps and a bellow pad to protect bellows from wear. This two tone accordion does not have bass reeds installed. The two main reasons being space limitations and that the majority of Conjunto and Norteno accordionists do not use them. A deluxe hardshell case and black 2.75" wide padded real leather straps are included with each accordion.
