I am selling one iPod mini that has been modded with a 256 Gb SD card.
Battery has been replaced with a new one.
The chassis is in good condition, has sign of use. It’s almost 20 years old electronics but this model is easy to service, maintain and upgrade. The bottom plastic plate is a bit loose and can be tightened with some glue or double sided tape, it is kind of convenient to have it easily openable for service and upgrades.

It comes in original box.
