This is a set of two boxes of Kohkento carbon rods, number 5000. It works well with all numbers and seems to amplify the characteristics of each. There are no breaks. I will pack them with double layers of bubble wrap, but please understand that if they break during shipping, I cannot be held responsible. *Please excuse any scratches or stains on the outer box. *The paint on the carbon rods may be chipped. *The images may be from past listings if the package design is the same.
