This was originally thought up for our Letter Writing Kit and is now available on it's own. A beautiful laser cut stencil that can be used in a variety of ways. The envelopes in the photo are A2 size, 4 3/8" x 5 3/4". We have some white ones that didn't come out as beautifully as we would have liked so those are on sale. Limited quantities! They work just as well as the original. This here is an original! Designed and made by Paper Pastries in California.
