The little seals (1/2 inch in diameter) are great for ephemera collections, journaling, mail art and more. The seals were originally used for legal documents and correspondence.These are not self-stick. They are gummed seals and need liquid to activate the adhesive. Due to their age, we suggest you test the gummed seals before wetting them - or, to be safe, use an additional adhesive of your own. We use a damp sponge to moisten our vintage stickers, do not lick them.From an old stationery store - very old stationery / bookstore and were very necessary way back when. There was a time when envelopes that were unsealed were less expensive to mail than those envelopes that were sealed. Imagine that! The store closed before WWII. These seals were from the early 20th century.Box not included. Box for illustration only.
