Letter set, 8 types. Each set includes 1 envelope and 2 sheets of writing paper, sold as a set of 8. One item is a single-sheet letter with 4 sheets of writing paper. No duplicates. Although unused, they have been opened, so they are listed as "like new." There may be clip marks. Please refrain from purchasing if you are looking for a perfect item. I also have other letter sets and stationery for sale. Discounts are available for combined purchases, so please feel free to consult in the comment section.
