I am not much of a reviewer, but I thought I would put in a shout for Fabriano Medioevalis cards and envelopes. They are made from mould-made paper, which seems an awful lot like cold press watercolor paper. Unlike some watercolor paper, both sides of the paper appear to have the same texture and feel. The cards have a seam that can be folded either way. The paper is smooth and absorbent, so ink tends to sink right in, but does not feather or bleed, and you can write and draw on all sizes with no show-through.
You can also buy envelopes for each card size. The boxes are not cheap (see the links below) but in comparison to buying cards, they seem reasonable enough.
I find them perfect for drawing a five-minute sketch to send off as a note card. The example below shows three quick drawings on the lager-size note card (drawn with Conid Fountainbel Bulk Filler with 1930s nib, and Sailor Jentle Doyou brown ink, and with apologies for my desultory penmanship).
