The quality is really beautiful--nice paper and good printing, which means a lot to me. (Did you know I used to run a big, messy, inky, noisy printing press? True story.) And the card sizes are a bit larger than standard business cards, so they have some oomph, if you know what I mean. They also have mini cards, which are half the size of the biz cards--so cute.
And while they offer some really nice designs of their own, the coolest thing about MOO is that you can use your own photos, and if you want to, a different picture on every card. Love it. You can also get books of little stickers, postcards, and greeting cards, all with your own mix of pics. Endless, possibilities. Sometimes I just go to their site to play, but like I said, I've already ordered three times, and keep coming up with cards I just need to have made.
I like them so much I joined their affiliate program. If you order from them through the link below, I'll get a little kickback. Sweet. I've decided to host only ads for companies I know and love and buy from myself. I'm sharing MOO with YOU, because I love you. Have fun!
