You asked for them, and here they are! All six mane ponies in necklace form! (I also have Princess Celestia). Each pony has a cute bow in her hair, hangs from a brightly colored chain, and had accenting lucite and swavorski beads. Each necklace is about 30 inches long, so they hang in the middle or below your bust. They look shorter in the pictures but I have the chain gathered in the back so they would fit onto my display bust.
Get your favorite while you can! You can see more pictures and buy them at Sugar Cube Corner: [link]
*UPDATE* I have these necklaces back in stock and I reduced the price to $30 each. I have about 10 of each character currently in stock.
