One case for SONY DD walkman. Please search online to make sure it will fit your model of DD walkman.

The seams of these cases have a thin plastic covering that typically has started to get sticky and peeling off due to age, so rubbing the seams clean of this covering is a good idea before using the case, to do that you can buy rubbing alcohol from a pharmacy and that will do the job very well.

This is an used item, it has not been cleaned, might require some cleaning before use.
