Keyboard harmonica case Pianica case Height 17cm, Width 46.5cm, Depth 6cm The exterior is quilted for durability! Velcro closures are used! *Regarding the slightly flawed item* The inner fabric is a little loose. (The inner fabric was slightly too large and didn't fit perfectly.) There is no problem with use!! The size hasn't been finalized yet, so this is a prototype! A keyboard harmonica I had at home, which was 13cm high, 45cm wide, and 7.5cm deep, fit, but it was a snug fit!! Please consider this size only if it's suitable for you!!
