This modern menorah by Pretti.Cool is made from terrazzo concrete. Each is individually hand-cast from a custom made mold. The colors are integrally mixed into the concrete, resulting in slightly unique colorations between menorahs.
Since concrete is a porous material, white, light or neutral colored dripless, beeswax Hanukkah candles are recommended. Colored candles can be used, but may leave a festive colored patina over time.
