Selling a few things on ebay, help with packaging?

You don't need the original boxes but you do need to make sure everything is secure and doesn't shift around. You can use any small sturdy box and any casing for the games or just the box itself but always package everything carefully. A shoe box like Aaron said might be okay as long as the psp is wrapped up and doesn't shift too much.

Make sure to list that you don't have the box or the game cases, some people like myself care about things like that.

Simply use a shoebox, packaging is not essential for second hand products as long as you mention this in the details panel.

I paid for a capture card on ebay ounce with tons of cables, the guy sent it via a shoebox and i didn't bother me, other then what was inside.
