These authentic Thai Buddhist amulets have a rich history. Thai amulets, charms and talismen are made by Buddhist gurus for various purposes: invulnerability, good luck, fortune, protection from evil, etc. Many Thai Buddhists wear or carry amulets of different kinds. They are in some ways comparable to "holy medals" in Catholicism.
An amulet may represent a famous Buddha image, may be blessed by a saintly monk or may be a more specific spirit to bring the wearer luck or to ward off misfortune.
