Late last year I made some custom boxes too. As gifts for my brothers and as custom box for the Special editions of MI, inspired by Laser's custom box at the time.
While it's awesome we can do this to great detail now, everyone should be warned there's scammers on eBay now using this technique to sell fake boxes for high prices. Just recently I think someone scamming a lot of honest collectors with fake sealed boxes. So I really usually add a little personal note in one of the bottom cover labels.
Both designs were created from scratch, using Laserschwert's awesome poster files for most of the the artwork.
