Are these 5"x 7" after folding?
These are flat cards, not folded cards. Here is a link to all of our A7 folded cards https://www.cutcardstock.com/collections/blankfolded5x7invitations
On the front of my card I'm only printing black ink, but on the back I plan to have a dark green background color with white font. Will the background color print well on this material? I was told at an office depot that the metallic card stocks don't do well in such a situation, but I really love the sheen!
We are unsure of what color you wanting from this line, so it is hard to answer the question about the printing. We could possibly print your invitations in house. If this interests you, please feel free to fill out our Printing Request Form
