The problem is, these aren't custom, they're repros of actual boxes. Some of the original Nintendo ones can go for quite a bit of money. He also has repros of some non-sport trading card boxes and action figure boxes. While his listings may say "custom" or "reproduction", the items he sells do not say it anywhere. If someone bought these they could try to re-sell them as original boxes down the road, and unless you know what to look for, could be duped into buying a repro being passed off as original.
