These strings are manufactured in Germany and are the softest co-poly I have tested to date.
Note: "Energy Pro" had the highest ever test scores by independent string testers and in "blind" tests with players who did not like "polyester strings" received the best ever rated string. (A lot of converts to this very soft polyester string!)
I will offer the first five customers restrings for £14
(Note: only the blue will be available at the moment)
