What is Reddit's opinion of DEEZOMO High Quality PU Leather Credit Card Holder with 26 Card Slots - Book Style - Size 4.2L X 3 X 0.7 Inches (Black)?

From 3.5 billion Reddit comments

I only carry a few cards at a time (debit, shared acct with SO, every day spending card, and whatever I'm trying to meet minimum spend on). For the cards I'm not currently using, I've been using these: https://www.amazon.com/dp/B0133TY852/ref=cm_sw_r_cp_api_PjfAxbW6RZ9CF

This is fantastic. Maybe this one? It's cheap on Amazon AND it comes in a ton of colors. 26 slots should be enough for most casters - Wizard gets 27 slots at level 20, Warlock has 19, Sorcerer has 21, Cleric has 27.

EDIT: Here's a plastic insert on its own.

Any idea where I can get a card case like this or something alike locally?
