Read nintendo 3ds and retail case

Product Name: Read nintendo 3ds and retail case
No charger. Comes with case, stylus, and game system. The game system doesn't read games immediately every time 80% of the time the game reads immediately. Sometimes they need popped in and out, sometimes blowing into the cartridge holder works. Pretty sure the connecting pins need a slight cleaning. Good condition otherwise. Left a game running for 1 hour and the system showed full bars. The retail case has some wear.
