I have very fine hair,the diameter is the perfect size for hair like mine. To my surprise the locks are very soft and flexible. The color is spot on. There is a smell that they get when wet, however the sellers were very professional and supportive to help me. You can tell that the ladies truly care for their products and their customers. I feel very confident in this set. I also feel very valued and educated as a customer. I am a cosmetologist, so I understand how meaningful it is to feel your best, and truly, I haven't felt better! Thank you ladies! I appreciate you! This is the (storm) set.
