A box of DL self seal window envelopes.
They've been sitting around for quite a while so I cannot guarantee the adhesive will work, they might need the assistance of a bit of tape. I'm listing the quantity as one but you don't have to take the lot, I'm happy to split them into smaller quantities as I don't anticipate most people needing that many.
