Chako,I think I've found something that would be more suited to heavy collectibles than the cheap wood one I bought. And it has more space and is only $100 more than what I spent on that wood one. My issue is that I won't be getting away with putting a tool cabinet in a bedroom. But, this is a good neutral color and looks more like a file cabinet than a toolbox.https://www.containerstore.com/s/storage/storage-drawers/bisley-silver-8--10-drawer-collection-cabinets/12d?productId=11000867&country=US¤cy=USD&utm_source=tcscompshop&utm_medium=feed&utm_campaign=google&cid=cse:PLA&gclid=EAIaIQobChMIuPGq0veT3AIViWSGCh0KKQSqEAkYBiABEgJFNvD_BwEI am looking at the 10-drawer model. 2 of those would likely house my entire collection if MTs and modern folding knives with sheaths/accessories.
You can use wood-like wallpaper to made it look like a wooden cabinet. Or a thin sheet of real wood.
Collecting girlfriends sounds like a very expensive and troublesome endeavour. My limit is one at any given time.
