The cards I got, are original Herlitz cards. White paper and blue lines. They are pretty thin, but not too thin or lapprig. It can be good to write them (only pen I have not tried). Of course I had already times thicker Herlitz cards, but the slightly thinner are dearer to me because space. For the price definitely a good deal. I'm very satisfied. I am only because of the comments, shied away, but I am glad that I ordered it.
