I had this wonderful paper card file box for over 22 years, and it has finally bit the dust! So I designed one for me (and one for etsy), with all the features I'd like to see a card box that has to sit out on display. Mine is made of fabric and chipboard, with glued and machine sewn joints. The trim is sewn on, not glued, and the measurements are based on the biggest envelopes I have. I made 8 dividers for the inside, out of poster board.
