My son seen these while I was showing him my favorite website. I surprised him with the #3 he was coveting.
Could not believe how much it was able to hold. So, I had to get one for myself. His is Ballistic, which looks very sturdy. I chose #4 Halcyon as I travel a lot and wanted to be able to clip it inside my bag. No more worrying if I set it down somewhere. Carrying 7 cards but I could easily carry more. (I don't want to.) Use the outside pocket for tip money or receipts. My children tease me that, since COVID started, my wallet gets smaller and smaller. This is as small as it gets. Tough material, super lightweight, and goes virtually unseen in back or front pocket. Love it!
