Well, in my opinion, I think that physical invitation cards went out of style, I think the same as you do that those physical cards are somewhat tedious and sometimes tend to get lost among so many papers or simply deteriorate drop some water or just wrinkle or break. The past if these physical letters were fashionable, but right now with so much technology and inventions, because the invitations should be by means of email or text messages to the cell phone. So, better are the invitation cards by electronic means.
