All of our banks are made from only the highest quality ceramic, known as dolomite, for increased durability. They feature a base that is deep glazed, insuring that this essential color doesn't wear off with repeated handling. To finish things off, we add a shiny finishing that keeps the colors of all of the underlying components locked in place, meaning that you never have to worry about compromising the quality of the bank with repeated use. - Piggy Bank needs 2 triple A batteries
