THE FUTURE OF COATED STRINGS ARE NOT COATED. Welcome to the next generation of extended-life strings. La Bella Vapour 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 Vapour 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 Vapour Shield is unlike any other string. The entire surface and full-length of all strings are treated with a nucleated polymer vapour 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 Vapour 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 Vapour Process Slick mutated surface is resistant to oil and grime 5-String Set String Gauges: . 040, . 060, . 080, . 100, . 118 Made in the USA with American Wire Packaged using MAP Technology (Modified Atmosphere Packaging) to prevent tarnishing and ensure freshness
