Very sturdy hardshell case for electric guitar. Keys for lock are included. Interior dimensions are 39.75 L x 12.5 W x 3" D (Case cavity is 2" deep and the lid cavity is 1" deep). I used this for a few months, then got rid of the guitar I bought it for. This is probably best for a solid body guitar, as neither of my semi-hollow body guitars will fit. The top and bottom sections are each 19" long.
