This is a super heavy duty concert ukulele case in almost perfect, unused condition. This is an older model from Reunion Blues, a renowned maker of road-worthy gig bags for stringed instruments. I suspect that this case model is superior to the current RBX concert case model. The case is shown with a William King ukulele with extra long headstock and it fits fine. Dimensions listed below: Total exterior length - 28" Exterior width - 12" excluding handle Exterior depth - 8" including straps and storage pocket Interior, exterior and side dense padding - 1" plus all around Interior Length - 25" Interior width lower bout - 9" Interior width upper bout - 8" Interor width headstock area - 6" Interior depth - 4" Neck rest to case bottom - 13"
