While cleaning, I found this in a cardboard box. I wonder if it was a Pringles potato chip promotion? I'm not sure when it's from, but it's definitely more than a few decades old. I don't have the necessary environment to use this, so I honestly don't even know what it is m(_ _;)m I don't think it's a music CD, so it's probably best to be careful about putting it in a CD player, just in case. Please read the instructions on the box carefully. The case is beat up, but the contents are unused and new. Only those who are okay with that, please consider purchasing. m(_ _)m Photos are attached. Please enlarge them to read the product description. Thank you for looking.
