Thank you for viewing! (´▽｀) Very old connection code. The package has been opened, but it has never been used. It seems to be a code for recording from a portable CD to MD, and I don't think it's used very often these days. Due to home storage, the outer box is dirty, and the plastic opening is torn, but the code is unused. Is there anyone who can use it? ⚠️Please purchase with the understanding that this is home storage and has aged over time. *Shipping will be via Nekopos until September 30th. Thank you.
