Letter Set Lucky Bag No identical patterns 2 sheets of letter paper per envelope, in a set of 1, with 50 sets, all with different patterns. Actually, a few extra are included as a bonus. For letters, decoupage, materials for handmade crafts, patterns for resin, kirie (paper cutting), materials for children's crafts, display, and wrapping materials. Includes a variety of styles, from casual and pop like Korean style, to fancy and dreamy cute, and Japanese style, regardless of the genre. Not all are shown in the image. I used to write letters every day with different envelopes and letter paper, and I had a lot left over because I only used one set, so I'm selling them because it's a waste. Shipping included, and it's a great deal. Although the package has been opened, they are of course new and unused, but please understand that they have been stored at home. No returns or exchanges, please.
