The LONGEVO strings combine traditional craftsmanship with the latest innovations.

These strings are shielded with a nanotechnology treatment that creates an imperceptible nanofilm that gives them an exceptionally long lifespan and also makes them suitable for those allergic to nickel.

This eco-friendly series of strings is completely free of chemical products, completely ecological and biocompatible, without affecting tone and feel, tension, intonation and reliability!

Mark Strings are manufactured in Abruzzo (Italy) using the best and selected materials with ultimate quality controls, in the best tradition of high quality production.
