We get a limited number of washed and dried cow tails each year from the USA.
These are nice, full tails. They are clean and nice to work with for a variety of craft purposes. The tanned cow tails are a little softer and more flexible than the dried cow tails.
The washed tails are 20" to 38" long.
Cow are not endangered. The cows were not killed just for their tails.
