Scarabs were used extensively in Egypt and became popular in certain time periods, even being reproduced outside of Egypt, mainly in the Levant, or its environs. They were also produced in far greater sizes (paperweights, and larger), and because of their flat bottom surface, became common as a form of "Commemorative Scarabs". They became common with the Famous 5, produced by Thutmose III, and later in the reign of Amenhotep III.
