Roma Plastalina is an extremely versatile oil and wax based clay that does not contain water, is not affected by heat, and will remain pliable indefinitely. Used by professional and amateur sculptors alike, Roma is one of the most popular sculpting and modeling clays on the market. Roma No. 2 is a medium consistency clay, often used for busts, portraits, and detailed figurative sculpture. It's firmer than Roma No. 1, but still works and tools easily.
