They were obtained from a giveaway a couple of years ago if I recall and I still have them sitting in my inventory. If you are interested in one of them feel free to name a price and since they are untradable I will have to attach it to some armor and give it to you (if you are buying these for a reasonable price ill craft what you want to put it on).

Feel free to add me/send me mail to negotiate, my ign is Pieguy.
