Lifespan 2.0 core-and-wrap protection
The patented treatment protects both parts of the string against corrosion without compromising tone.

Independent shopping perspective
These Custom Light 11-52 acoustic sets combine 92/8 phosphor bronze with Martin’s patented Lifespan 2.0 protection on both the core and wrap wire. The treatment is intended to guard against corrosion while maintaining tone, and the strings are made for a smooth feel that reduces finger drag. With three matched sets in the package, they suit players who want to keep the same protected phosphor-bronze setup on hand for repeat changes.
