This is a soft case for a contrabass (upright bass). It is a standard domestic size, equivalent to a domestic 4/4 (or overseas 3/4) size. The padding is quite thick. The top part of the zipper (headstock side) is difficult to open and close for about 10cm. I have never felt it affected putting the instrument in or taking it out. Otherwise, there are no particular problems. However, this is a used item, so we are looking for buyers who understand this. No claims and no returns, please.
