Nanofilm shielding
An imperceptible microfilm is applied to support exceptional longevity.

Independent shopping perspective
Longevo Series 11-49 electric-guitar strings use nickel-plated steel protected by an imperceptible nanofilm. The shielding is designed for exceptional longevity without changing the strings’ tone, feel, elastic properties, intonation, or reliability. For a player replacing an 11-49 set, the appeal is straightforward: a protected nickel-plated steel option intended to preserve the playing response and tuning accuracy associated with the strings while extending their usable life.
