Got a new wallet but the card slots are slightly too small for my business cards, so need a card case. Sounds like leather is the way to go. Looking for relatively conservative (no alligator unfortunately), no (or very subtle) maker's mark and thin case with high quality leather. Don't love the BB shell, Alden is a bit thick. All the "etsy" makers like Mitchell like to stamp big, beautiful inappropriate for the finance world contrasting logos on everything.
Willing to wait for 4-8 weeks and just continue with a Muji if they are small and need lead time.
