Soft but Thinner Than Expected
Color: Pink, Color: Pink
This cashmere scarf is very soft and pleasant to the touch. The color is really nice. It is not too bright and is a bit darker than in the pictures, but still very close to the description. What I did not expect is that the scarf is not very wide and is quite thin. Because of that, I was a little disappointed.

A pricy scarf, but worth it for its warmth and softness
Color: Pink
Came in a box that would look like it was be used as a gift. Scarf was really soft and warm and the color matches the imaged shown on the product images. The length and size was true to what was said. Gave this as a gift for valentines day and the other person was happy to receive and and like it as well. I will say that the price of the scarf is pretty pricy but I guess that's why you have to pay for a pretty good quality scarf.
