The console itself is in good condition, a slight wear mark to the top of the hinge lid but not serious and does not affect use. The box is solid, there is no insert for the box.
Every now and again you get the flashing red light but this I believe is due to the game cards being dirty. I don't want to go rubbing around on them as I do not have the right stuff. But usually a good old blow of the cartridge gets them running sweet.
