Herbin sealing wax is made with several natural elements: pine resin, ground limestone, lacquer and a dye made from cochineal—the legendary red dye that was once one of the world’s most precious commodities. Supple sealing wax does not crack, chip or break. It can be cut, so it is often used on bottles. Letters and cards with supple wax seals can be sent through the mail if the letter is hand-cancelled.
