I bought these to replace an old insert that was held together with tape and prayers. Initially I was pleased with the number of slots and how snug my cards were when I placed them in the sleeves. The joy of my "great" find evaporated as some of the sleeves began to burst at the seams as I attempted to remove the card for use. This is when only one card is placed per slot as they are not designed for multiple cards. The plastic tab that slides into the wallet to secure is also too small for my wallet, which isn't Alpine Swiss, but I made it work with little circles of Velcro to keep it from falling out entirely. This probably only works better for loyalty cards or business cards in an Alpine Swiss wallet.
