Elixir Acoustic Guitar Strings 16569 (Set of 3, 16052), Phosphor Bronze Ultra-Thin Coated

Genuine elixir strings have a nano-coating layer on the outer surface, providing a smooth tactile feel.

Prolonged use of authentic elixir strings may result in the coating wearing off, causing a "fuzzing" effect, which is a unique characteristic of genuine elixir strings.

At the head of the string (the end inserted into the bridge), there is a clear demarcation between the coated and uncoated sections, marking the starting point of the coating. This feature helps to identify authentic elixir strings.

The coating distinction is more noticeable on thicker strings; the 1st and 2nd strings do not have the coating.
