The colors of your life mezuzahs are inspired by the Prism of Kabbalah. Each mezuzah has a fused glass mosaic of color on the front that represents a specific characteristic. Blue represents love. The gift of blue is for support, learning, council, friendship, and unconditional love. The Mezuzah measures 3 1/4" in length, 3/4" in height, and 1/2" in width.
