Apple IPod Touch. 
5th generation, Model A1509.  
I am assuming it is a 16g based on model# and serial#.  However the box indicates 32g so I’m not positive.  I’m listing  it as a 16g. 
Includes original clear plastic box, charging cable, earbuds, iPod and even the Apple stickers!  
Nice condition! 
Tested and holds a charge well.
