Game cases for NES cartridges?

[oRBIT2002]

Can anyone recommend any nice looking game-cases for NES-games? I'm not talking about protective covers but replacement boxes (that uses covers aswell). I've seen the UGC boxes but I think they look to big? The BitBox NES Game case looks pretty cool.
Anyone got any hints? Would be great if these boxes would be available for purchase in Sweden aswell.

So like Sega Genesis cases, but for the NES instead?

Haradius Zero came in a really nice feeling case from customgamecases.com, feels kind of like what a DS case would feel like if blown up to NES scale. No lip around the edge and relatively compact feeling. The dimnesions are slightly larger than a NES box, especially the thickness, but not far off.

I did a run of games using Bitboxes and although they're nice in a different way they are a bit more fragile feeling. They kind of remind me of the cases old Disney VHS movies came in. A bit larger than the other cases with a lip around the edge, but and plastic is more prone to crushing.
