I was cleaning out my skibuilding stuff from my thesis project and I found my set of Head Intellifibers. The 2 bias fiber chips I have are the ones used in the Head ski construction and the 3 rectangular fiber chips I have are used for Head Tennis. These piezo fibres are new and have never been installed, just tested on a oscilloscope. There is some light tarnish on the leads, but otherwise they're in near mint condition.
