I got these today, after ordering them 4 days ago, and I love them! Definitely 100% human hair and it's thick. It also came longer than expected, I ordered 18 inch and its almost 22 inches. I have a very short pixie cut, as I've been growing out a mohawk, so its about an inch on the sides and 3 on the top and back and these fill it very nicely. I'll be posting pictures after I dye them and my own hair.
