"Toofy" the necklace is an anomaly because nobody knows if it's a bone with a penny inside, and is that why it is both smiling and frowning? The backside looks like a gorgeous vase so whether you wear it front or back, "Toofy" is sure to be a great conversation starter or diversion at parties. This photo shows the front, sides, and back of the handmade pendant. Materials used: oxidized silver-plated stainless steel, polymer clay, copper, acrylic paint, glitter, swarovski crystals.
