This is a box of vintage medallion seals I found at a tag sale. The box stated that it contained 500. I have no idea how many were used but note that the box is mostly full. The adhesive backing does peel off of them without tearing. The adhesive is still tacky, but you would likely need to apply additional adhesive for your chosen application. Once the backing is removed, the foil seals are nice and thick--they feel like a piece of foil or heavy cardstock, not like a paper sticker. The box smells old so I am discarding it and will repackage the seals as shown in the last photo. I included the original box in the photo to give you an idea of how many there were if the box held 500. The seals have been exposed to the air in storage to freshen. From a nonsmoking, pet-free, climate-controlled environment. Check out my store! I'm happy to combine shipping on multiple purchases.
