Much of the information that you might be able to find about business cards tends to focus on things like the information they are supposed to contain, but suffice it to say that this is not the only thing that matters as far as business cards are concerned. If you want a card that has been optimized to every single extent imaginable, it helps to look at it from a variety of angles so that you can be certain that you have not missed out on anything that might have been important.
For example, did you think about what the shape of your Metal Kards would be when they finally get printed? Chances are that this slipped your mind due to the reason that you were so fixated on its design elements, but the good news here is that this is not all the challenging of a thing to figure out. The average shape of a business card is rectangular, and they are most often two inches in height and about three and a half inches in width.
Sticking with the rectangle shape an simplify matters greatly for you since your printing service would not be forced to break out new and unique machinery to fulfill your artistic vision. There are some who might prefer square cards or even round ones, but these are usually nothing more than gimmicks due to the lack of practical value that they provide. You should never let yourself get carried away by opting for unnecessarily out of the box business card shapes. The rectangle is the standard shape for a reason, and you would do well to not rock the boat.
