This is a USB converter cable made by I-O DATA. It was originally an accessory for an external CD-R/RW drive. I was using a separately sold cable, so this one was stored unused in a cardboard box. As you can see in the photos, the metallic luster is still intact and it's in beautiful condition. (Operation has not been confirmed due to lack of environment.)
