This is a pianica case ^_^ It's a single-layer construction using quilting. It's not denim fabric. The inner seams are finished with bias tape. It opens and closes with a snap. The size of the bag part is 51.5 cm wide, 22 cm high, 8 cm deep, and 43 cm at the bottom✩ A 32-key Suzuki pianica will fit, including the hard case. This is a handmade item. It is not perfect like a mass-produced product, with slight misalignments and distortions in the stitching. Please understand this before considering a purchase. Thank you very much✩ #PianicaCase #PianicaBag #Simple #Plain #Quilting Pattern/Design...Plain Type...Pianica Case
