Elixir® Strings with original POLYWEB coating have a balanced tone and smooth response. They feel comfortably smooth and reduce finger squeak. Elixir® Strings are coated in a unique way to protect wound strings from your DNA and other contaminants. A flexible, strong, yet micro-thin polymer tube defends the Critical Zone of Tone from invading enemies. Nothing (including the coating) gets between the windings. The result? Strings that sound and feel their best three to five times longer than ordinary strings.
