I find the Pro binder really very good. This is my third and I use it for my cards out of the X-Wing game. The pilot cards fit with casing without problems and remain there where they should stay. 'm Hardly worry that I might lose a card by sliding out. The small cards I PCKE as few side by side in a card slot that fits quite well. However, the slip a bit and it is abundant in the follow up on when mans wants tidy. But all in all it works well, the cards are excellently protected and secure.
