CD Player that is capable of playing MP3's

Hello all,

I am searching for a CD player that can play MP3’s. Do they exist? Not only do I need it to play MP3’s but I also need the casing to be clear/translucent.
I am searching for my son who is going to camp and the only electronic devices that are allowed must be “see through”
Would it be difficult to make something like this???

Thank you for your help! :slight_smile:
