I have a vintage round-back mandolin in need of repair and since I don't know if it's worth salvaging until a luthier examines it, I needed a case that wouldn't break the bank. This is perfect! I am happy to report that if the mandolin gets repaired, I will keep using this bag. The foam material is thick and rigid, very pleased with the protection it provides. All in all, exactly what I needed at a price point where there is no contest. Recommended!
