I have kept this carefully. It's in the condition shown in the third image, so it's possible that it has been opened (I don't remember). It's a set of 16 sheets of writing paper and 5 envelopes. I haven't opened it this time. From the outside, there are 5 envelopes, but I haven't counted the writing paper this time, so there's a possibility that there aren't 16 sheets. However, the number of envelopes hasn't decreased, and I feel like I wouldn't only use the writing paper, so they might all be there. That part is unclear, so I'm listing this item, along with another of the same kind, but I'm pricing this one slightly differently. Thank you for your understanding.
