Each chisel mark and texture is captured by molds, then individually cast from the finest composition stone. Glass-fiber reinforced concrete material has the durability of concrete but is much lighter. Will maintain sufficient porosity to age gradually over time. Volume is approximately 6 cubic ft.. Planter includes drainage hole. Rich detail and all-weather construction enhance our Vienna Garden Planter, reproduced from an early 20th century original in Barbara Israel's collection. Fruited swags and classical masks ornament the composition stone planter, which will weather gracefully over the years. . . . . During cold/freezing temperature times, planter needs to be emptied, raised off bare ground, and covered. To clean, brush off excess dirt or residue and rinse with water. Made in the USA.
