Customer Testimonial - "I recomend these knives. You cant beat the price. Save your money on the expensive knive sets. I have a set I paid 80 bucks for and these knives are just as good. In color changing knives you dont get what you pay for. Buy these instead I am buying another set so I can do more routines".
