When we were selecting those cards, there were quite a number of options to choose from. However, once we decided on a design, the customization process was very straightforward and easy to navigate. The one limitation was the inability to add completely new fields or elements like additional text boxes - we could only modify the existing template. But in the end, we're extremely pleased with how the cards turned out. And I'm delighted to say that everyone who has received one of our cards has been very impressed by our choice. It seems we made an excellent selection.
