Rotten Sprouts Card Case

I am a well-known despiser of Brussels sprouts, and so (of course) this Christmas someone gave me the ‘Rotten Sprouts’ card game as a novelty gift. We weren't expecting much but we played it as a family and rather enjoyed it. Unfortunately the supplied packaging was not great and we therefore didn't expect the cards to last well - so I printed up this rather nice bayonet-fitting case for them. Perfectly reasonably and not at all silly overengineering.
