.014 There are 5 products.

The folk guitar string you purchased is 0.014 inches (or 0.36 millimeters) thick. When guitar strings are labeled with a number, as in this case with "0.14", it is usually an abbreviation for that thickness in inches.

In general, thicker guitar strings produce a more powerful and richer sound, but can be more difficult to play because they require more force to be pressed onto the neck. Thinner guitar strings, on the other hand, are easier to play, but can lack the depth and power of sound of thicker strings.

It is important to choose guitar strings based on your playing style and personal sound preferences.
