If paper could be sex these envelopes would get me pregnant

Buying these envelopes was a leap of faith for me, so let me tell you about them. The paper is a good heavy stock. The inside of the envelopes (reverse side of the paper) is matte with a lovely smooth grain that would qualify as gorgeous black paper on its own. The outside (right side of the paper), however, is simply amazing. It's as if it has been brushed, with a velvety softness that I have never encountered before, and it is even more matte than the reverse side--it's like it traps light, I have never seen such a dense black before! I experimented on them with many different white ink markers and the results were gorgeous. It almost gives a chalkboard look. (For the nerds: the pens I played with were a Sharpie oil-based extra-fine point paint maker, a Sharpie water-based fine point paint marker, a Sakura Gelly Roll 08 gel pen, and a Posca bullet shaped .7mm pen.)

Bottom line Yes, I would recommend this to a friend
