Product review (4 stars): Cant say how good they are
I've ordered this rollers for different project (to modify my snow blower). I've contacted the seller to ask him if the core is brass or steel, but he did not know. So I took a chance to order it, and found out they are steel, so for know they are not working for me. One star less, because of the seller's answer. I know he doesn't care, but for you to know if you have same question.
