Bought two sets (Rose & Pistachio) in 2016 and am still using them occasionally to send to friends/loved ones. Material is quite hard and very sturdy, so it'll last during its journey across international waters, but isn't super friendly for anything other than rollerball pen or felt pen writing. It's a bit ink resistant (not proof) because the material is so hard, so if you use a gel or a calligraphy pen, you might end up waiting for the entire night and then some for the ink to dry.
Otherwise, it's very elegant and incredibly lovely as a blank card. The colors are true to screen, the rose being a very cute pink hue and the pistachio a steady green.
Considering the costs, this was not a worthwhile drop. In fact, following a pause in purchasing, I've noticed Massdrop is now offering not so infrequently overpriced warez. If you buy cardstock (e.g., Kelly's Paper) and purchase Deckle sizzors, you'd be out a third 1/2 th out what I paid and have something that is at least equal. I'd stay away from future offers. In fact, I had purchased 20 gold leaf Giandio notecards with envelopes for $10.95 and they are multiple times more beautiful to look at. And, if I purchase paper it is assumed thaf it takes ink, so I will not assume that that should justify elevated prices regardless what some of our "connoisseurs" argue.
The stationary size, quality and its fountain pen friendly aspects make this item a great purchase. Hands down very impressive and I will order again if were to become svailable.
I love the stationary, the only thing I would do differently would be to have a full sheet option as well. It is absolutely lovely to write on with my fountain pens.
