Electric guitar strings made of nickel-plated steel, offering a bright tone and long life. I am selling these as I have not had the opportunity to use them after purchase. They are new and unused, but I purchased them from a store two years ago, so there may be some aging. Since they have not been opened, I cannot guarantee the condition of the contents. Please inquire about any unclear points beforehand, and please refrain from returns or complaints after purchase. The following is quoted from the official website: Electric NANOWEB Coating NANOWEB® coated electric guitar strings are the standard Elixir® electric guitar strings, providing the same presence, impact, and delicate expression as conventional electric guitar strings, while offering a sound quality lifespan that is incomparable to conventional electric guitar strings. * The only coating technology that completely covers the wound strings prevents dirt from entering the gaps in the windings. * Higher sound quality and longer life compared to other coated/non-coated strings. * You can play whenever you want. * Improved playability with a smooth feel. * Reduced finger noise, perfect for both live performances and recordings. * Anti-Rust plain strings with corrosion-resistant processing are used, achieving a long life for all strings in a set. * Reduces the frequency of string changes, allowing you to focus on playing.
