Korg DS-10 Synthesizer Plus (Nintendo DS, loose)

The upgraded version of the Korg cartridge for the DS, that allows you to turn your console into a full blown digital synthesizer. 
Super fun and cool little tool! 

Again, please be aware this is the PLUS version, which is much more rare and expensive than the first synthesizer, that Korg released. 

Condition: Great, but loose game only.
