Review on Lungogo Minimalist Organizer: Streamline 🗂 Your Life with Automatic Aluminum Efficiency by Billy Donalson

It contains 6 or even 7 cards. I've been using the first and most used for about 3 years, which is more than acceptable. I suspect that storing 7 cards in the sleeve wore out the connection, so "my fault"! And in any case, when the lever slipped out of the case, I fixed "push"! My other is in good condition but rarely used. Bought a new one as insurance "just in case”.
