From Troutline:-

We are proud to provide to all  our friends the best winter roe deer hair in natural colors: Troutline Winter Deer Hair!  We received these skins only from from game animals ( and only from deer hunted in Transylvania ). We select them before tanning process in order to provide the best hair pelts for our clients. After tanning we cut in pieces and  we re select them again. We spend a lot of time but it's worth it! In this way we obtain the best product and we are sure that our deer hair has the highest quality!
