I realized last week as I signed up for Gamercamp that I didn't have any up to date business cards, so I had a bit of a rush since I had about a week.
Suddenly my whole afternoon had vanished into designing a minimalist card that I needed to submit that day. I had been eyeing the Moo Luxe cards for awhile, but had procrastinated on getting them. Fortunately they have some great turn around time, and less than a week later I have them in hand.
My immediate impressions are that they are thick. Really thick. It's on the edge of being too much, but in hand they have a very distinct feel so I'm counting it as a positive. I had ordered a free sample card many months ago so it wasn't entirely unexpected, but as a whole stack it's emphasized even more. This is because each card has a middle "sandwich" layer of pure black (other colours are available too), which I think adds a great accent to a minimal design.
Overall I'm pretty happy with them, and hopefully I'll get a few of them out during Gamercamp this weekend.
