Hello, I'm Stefania Gotzer. Welcome to Business Daily from the BBC. It's known as one of the most expensive walls in the world and even a scarf can cost you a few thousand dollars. Why would a scarf

be that expensive? Well, the fiber from

Bikunia is the finest of all natural fibers. You heard it right. We are talking about Bikunias,

a fairy mammal, just over a meter tall, which is the smallest relative of llamas and alpacas.

Demand for their silky wool once led them to near extinction,

but now it has become the best tool to save them. In Peru, we say vicuna is Vikuna salvada.

Shaped Bikuna is like a saved Bikuna. So what makes Vikunyaia is like a Seibet Bikunia wool so special and whose pain four-figure sums to wear it?

We find out on this edition of Business Daily.

If you've never seen a Vikunia before, close your eyes and imagine a llama.

Now shrink it to half that size.

Paint its fur the color of a camel and imagine a white belly at the front of the neck.

so steer away from the fluffy look of alpacas.

That's a bikuna, the animal that produces one of the pricest wolves in the world.

A kilo of its fibre usually costs hundreds of dollars and garments made out of it aren't easy to find.

Even the big designer brands will rarely have them in their stores,

but a small number of individuals around the world are paying large sums for them.
