A Thai Buddha amulet (Thai: พระเครื่อง), often referred to academically as "votive tablet", is a type of Thai Buddhist blessed item. It is used to raise funds to help the temple's operations. A Thai Buddhist monk will give an amulet to Buddhists as a "gift" after they donate money or offerings to the temple.
