This is a pianica case✩ This set includes a detachable, adjustable shoulder strap. It's a single-layer construction using quilting. There are small black dots on the inside of the quilting, which are from the cotton material and are not stains. It opens and closes with a snap. The size of the bag is 53 cm wide, 21 cm high, 8 cm deep, and 44 cm at the bottom ^⁠_⁠^ A 32-key Suzuki pianica will fit inside, including its hard case. This is a handmade item. It is not perfect like a mass-produced item, and may have slight stitching errors or distortions. Please understand this before considering a purchase. Thank you. #PianicaCase #PianicaBag #Ballet #Quilting #Girls #ShoulderStrap #ShoulderBag Pattern/Design...Lace Type...Pianica Case
