This Nagini Slytherin pendant was made with polymer clay and resin. The intricately designed polymer clay frame is painted silver with a metallic green background to represent Slytherin's house colors. The silver snake is sealed in the center of the pendant with a clear solid resin half circle, since in the book, Voldemort placed a charm on Nagini so that she was inside of a protective bubble.

The pendant's diameter is 1 1/2 inches ( 4 cm ), and is strung on an 18 inch ( 46 cm ) dark brown braided cord, and has a lobster clasp closure.
