1. Burning: If the store allows it, use a lighter to burn it gently. Look carefully to see if there are small black particles. Smell it again to see if there is a smell of burnt protein. If it is fake, Yes, it smells like burning plastic.

2. Weigh: weigh it with your hands when purchasing. Because cashmere is a very soft fabric, lighter than wool, pick up the product and weigh it when purchasing. This is an easy way to distinguish cashmere products from wool products. Real cashmere scarves are very light.

3. Look: If the store does not allow burning, you must first choose a brand that emphasizes credibility, quality and reputation. Never randomly choose cashmere products that do not have a factory address, trademark, or cashmere content. Then look at the quality of the product. A high-quality cashmere sweater has a soft luster, plump suede, and strong wool texture. It has a layer of fine velvet on its surface after milling, and the density of horizontal and vertical coils is even. This is more obvious if it is looked at under bright light.
