How to distinguish the real from the fake fur?
The silver fox fur is oftenly issued of a fox-dog’s fur. The fur of a beaver is usually issued of nutria, which is the way more cheaper.
You can easily determine if the fur is a fake or not, by a simple touch:
Rabbit is soft. Minks’ guard hair is very harsh, isometric and unarmed. Marmots’ hair is of the same length. Arctic fox has a thick underfur and a short axis. Beaver has a fluffy fur. Karakul has a moire patter on its hide. Its fur also glitters. Nowadays sheep are mainly slaughtered rather than sold as a high-quality fur.
It is more advantageous.
