This is the SONY MDR-100A stereo headphone SCANDAL model. Thank you for viewing. I purchased this when the collaboration model was released, but I ended up not using it. Currently, there is no noticeable deterioration of the ear pads, etc., but since it has been several years since the purchase, please understand this before purchasing. The outer box is also included, but it has some mold (see image 6). A dedicated case purchased for storing the headphones is also included (see image 5). *The case is not a collaboration item. Shipping is planned via Mercari's anonymous delivery service. How about adding it to your collection? Immediate purchase is welcome. #SCANDAL
