Sturdy, not floppy
Received these just in time to do a Keratin treatment.  These are heavy duty, and won't flop/ bend easily, like many will.  The rat-tail comb was great for sectioning my hair, and it's a fine enough comb to do a great job distributing the product evenly.  The wider-tooth combs were outstanding for detangling after the clarifying shampoo - and that's saying something, since my curly hair already has a tendency to tangle, and for the treatment, you can't condition between washing & applying the keratin product.  Very happy with this purchase.
