I have a California Body Hour glass shaped Dulcimer, which is wider (8") and deeper than a standard size mountain dulcimer. Both the width and depth would not fit a standard dulcimer case. This case is one of the few that would fit my dulcimer. It is well built. The zippers are heavy duty and move smoothly. There are extra pockets for the extra's you might need, e.g., noter, picks, music, etc. I have extra room and may add some foam padding to keep the dulcimer in place and extra protection. The case itself has heavy vinyl to protect from minor scratches. I am very pleased.
