This is a pianica case (^-^). This is a single-layer case made with quilting. It is not denim fabric. The inner seams are finished with bias tape. It opens and closes with a snap. The size of the bag is 51.5 cm wide, 22.5 cm high, 8 cm deep, and 43 cm at the bottom. A 32-key Suzuki pianica will fit, even with its hard case. This is a handmade item. It is not perfect like a mass-produced product, with some stitching errors and distortions m(_ _)m Please consider purchasing with this in mind. Thank you! #PianicaCase #PianicaBag #Simple #DenimStyle #Quilting #Quilt Pattern/Design...Solid Type...Pianica Case
