Soft N Style 60 piece Rubber Rod Set
I have shoulder length hair, I purchased some other brand kind from Walmart, and didn't really care for them.  This set though, I really love.  My hair has different lengths so I really appreciate the fact, there is so many different sizes.  I was a bit apprehensive about some of the reviews due to the fact some said some colors didn't bend, and had a smell to them.  Mine all bend very well,and have no smell to them at all.  If your hair is hard to curl, these are great!  I haven't left them in over night, but sometimes when im in a hurry, I take a spray bottle, lightly mist my hair, and leave in for about 20 min.  I have the nicest curl.  Give the Rods a try, the price is right for so many rods.  I nearly gave this much money for far less from Walmart, and am not happy with the walmart ones.
