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.

Cute, warmth and quality!
Size: Small-X-Large, Color: Undyed Beige, Size: Small-X-Large, Color: Undyed Beige
Comfortable, cute and kept me warm, but not too hot. The cashmere felt great, extremely soft, and it didn’t mess up my hair like a synthetic hat can. We were out in subzero weather, and this baby did its job!

Perfect fit for a small woman or teenager
Size: Small-X-Large, Color: Light Gray
I think this beanie is a great price for the quality. It’s about as soft as wool can possibly be. I was very impressed by the packaging. It made me feel like I was opening a luxury item, which is nice because it was reasonably priced. They even included a bit of extra yarn in case it needs repairs someday. It does fit a bit snug. I have a small head, so it might be uncomfortable for someone with a bigger head. I definitely would NOT buy this for a man. It’s comfortable for a small female only, or a teenager. Overall, I think it’s a good hat for the price.
