Slinky Paradigm Electric guitar strings provide unprecedented
  strength and longer life while retaining 100% Slinky tone and
  feel. Ernie Ball's industry leading ultra-high strength steel is
  included in both the wound and plain strings along with a
  patented reinforcement at the ball end twist of each plain string
  to provide superior tensile and fatigue strength for strings that
  lock into tune fast and hold up under the most stressful playing
  styles and conditions. The coupling of Ernie Ball's Everlast
  nanotreatment with breakthrough plasma enhanced wrap wire
  provides added corrosion resistance and reduced accumulation of
  tone-robbing buildup and debris.
