I received my new QSL card last night, but I discovered a serious problem.

Because I didn't delete the unused layers, the two layers were overlapping. This caused the color of the card to be darker than before. Although it was just a minor flaw, it still had a significant impact on the actual effect. After communicating with the printer, I decided to pay half the cost and have them reprint it.
Now, dealing with these 450 discarded cards has become a difficult problem. I'm curious to see everyone's creative ideas! Haha.
