Black Leather

I had 2 issues I ran into. My first one was that it jams often with only 3 plastic cards in it. I had my CA drivers license, a credit card, and a hotel key. It works fine sometimes, but have experienced almost being locked out of my hotel room because all 3 cards were jammed inside of it. I tried to get the cards out for nearly 30 minutes each time. Eventually I was able to get my cards out and had to resort to only having my ID and credit card. I had to leave my hotel card in my pocket instead. I didn’t want to risk having my hotel card stuck when I needed it. I feel confident using it if I only use two cards in it.
My second issue was experienced at airports. I took it with me to two airports and got held up by TSA agents every time. They wanted to know if it can be taken a part and if it can be used to conceal other items aside from cards. They eventually let me go though, but not after inspecting the buckle and me explaining what it is, what it does, and how it works.
