Carbon Fiber Strips .057 x .177 40 inch (2)

This product was exactly as described. The size is right on the money. I am using it to strengthen the wing of a foam air plane(the wing flaps around like a bird right now.) After looking at the carbon fiber strips, the wing should be fine. The only bad thing, and this goes for all carbon fiber, you must be VERY CAREFUL when you cut it so as to not breathe in the dust(really bad for you if you get too much). This is for all carbon fiber not just this retailers products. As with anything you should take the time to learn about what you are working with,you may save yourself from problems later.
