THE FUTURE OF COATED STRINGS ARE NOT COATED. Welcome to the next generation of extended-life strings. La Bella Vapor Shield™ strings are like no other string on the market because the surface of the string is modified during the treatment process. Coated strings are now a thing of the past. NO FLAKES, NO CRACKS, NO PEELING. NO MUFFLED TONE. Using a highly sophisticated Ionic Vapor Process™ developed by Acoustic Science, proprietary compounds are activated in a glow discharge electromagnetic plasma, and the surface of all strings are modified. The result is a string protected from dirt, oil, residue, and tarnishing. Most importantly, string playability and life is extended without flaking or compromising tone. THE LA BELLA VAPOR SHIELD™ DIFFERENCE. The technology behind La Bella Vapor Shield™ is unlike any other string. The entire surface and full-length of all strings are treated with a nucleated polymer vapor material that requires hours of complex prep and processing; no spraying or dipping. The results are unmatched: TONE. BRIGHTER than typical coated strings AND non-treated strings. FEEL. The Ionic Vapor Process™ improves the string’s surface properties, resulting in SMOOTHER strings vs. both typical coated and non-treated strings. LIFE-SPAN. Lasts 5x longer than non-treated strings. ENDURANCE. No flaking after extended play. Impervious to grime, tarnishing and oil residue. Nickel-Plated Round Wound treated with Ionic Vapor Process™ Slick mutated surface is resistant to oil and grime String Gauges: .040, .060, .080, .100 Made in the USA with American Wire Packaged using MAP Technology (Modified Atmosphere Packaging) to prevent tarnishing and ensure freshness
