LOVE these notecards. First, you get many different designs (2 of each design), which gives you a great variety to select from when deciding which one to use for a particular person. Second, the quality of the paper and envelopes is super. Third,the fact that these are notecards (sort of like a postcard with an envelope) makes them great for when you want to attach just a brief note to someone. For example, I've used them to send a check to pay for something, to send tickets, to send a gift card, to provide directions, and more. The beauty is you essential get a postcard (although with a bit more space and a shape that's a little different than most postcards) you can put in an envelope and send off. How cool is that?
