As a business owner, that would be countless things that would be weighing on you and how much money you are spending on various things is definitely going to be at the very least close to the top of that list if not at the very top itself. The thing about business cards is that they have a tendency for being really cheap, but those business cards that you make are going to be really fragile as well and they would basically be little more than bits of paper that could fly away in the wind at any moment.
In spite of the fact that this is the case, lots of people tend to use them because Metal Business Cards are more expensive and they want to cut costs. That said, it is important to note that sometimes spending more money can make a lot more sense as a business decision at the end of the day. This is the case with business cards as well, because while metal ones are going to cost more, they are also far more durable which means that you would have to get less of them printed as you would know that the ones you had made are going to last a very long time indeed.
Hence, if you are asking whether or not metal cards are more expensive, it depends on how you look at it. While each individual card is going to be more expensive, you would need to get fewer made and the ones you get won’t be disposable either so you can save money in that respect. This shows that metal cards are actually cheaper than paper if you look at things the right way.
