I have been wanting a sample of mammoth hair of quite a long time. However, even with small and inexpensive samples, I am concerned about authenticity. There is a seller on eBay selling samples of mammoth hair in grams. Each gram seems like a decent sample, so I am tempted. However, I am not sure of the hair's authenticity.
