This is an original sacoche bag from Kawai Music School. It is a product of Onward. I received it at a recital. I took it out of the box, but my son is a boy, so he has never used it. It has two pockets inside, and I think it's very cute for going out, etc. [Outer dimensions] Approximately 26.5cm x 21cm (without gusset) [Belt length] Adjustable between approximately 70cm and 135cm I will fold it lightly and ship it.
