Works great with a few modifications
For us guys that have a traditional wallet with credit card slots the sleeves make an extra step in getting the credit card out. I slit one side of the sleeve lengthwise to allow the credit card to go into the sleeve from the top which makes it a lot easier to withdraw from the wallet. Insert the sleeve into the credit card slot and then don't have to remove it to remove the card. Card slips in and out. Added a little Scotch tape to the inside of the sleeve where there's a fold so the credit card wouldn't catch on it. Works great but pacsafe should make them like this.
