The system allows you to punch a border along the bottom of your cardstock seamlessly with no user error! I don't know how many times I've seen people try to fiddle with their border punches just to mess it up. Another thing that's great about the system is it's compactness. Once you have the ruler/punch set-up, all you have to buy are the cartridges that are fairly small and therefore storage is not an issue with this product. So all-in-all I am a happy customer and am looking forward to more border punches to add to my collection!
