As promised, here is the TecFlex packaging. The string is mostly smooth and has a slight gluey smell to it. I find it interesting they only gave themselves a 5 out 10 score on spin. Finally, somebody gives their string an honest score! I also cut my sets of the Volkl V-Twist. Based on the name Volkl, I thought it was a German string but it says made in Taiwan. Kind of looks like X-1 Biphase and has that nice gluey smell.
