Awesome product. Built well. Can keep some cash, and there are slots to keep some ID cards. And anything that EXACTLY has the size of a regular credit card goes into that aluminium RFID blocking case (maximum SIX cards). The way the ejector works is shown in one of the pictures I have uploaded. It's a spring mechanism. When the switch for pulling out the cards is used, the spring is loaded, and the ejector ejects every single card stacked in a way (first image) that would let the the user pull out just the required card. Very convenient. The case is stuck on to the wallet using some strong glue. Although it doesn't look like it's coming off anytime soon, it would still be fixable even if it does.
