Product Description These Elixir strings capture that unique tone and extend it 3-5 times longer than conventional strings. This means you buy fewer sets of strings, change them less often, and can trust that your guitar is ready to play when you are. All strings, both acoustic and electric, feature Elixir Strings' patented NANOWEB® or POLYWEB® coating and anti-rust plated plain steel technology. Elixir Strings are the only strings that cover the entire string, not just the winding wire. This prevents corrosion and contaminants from accumulating on the surface and, most importantly, from collecting in the spaces between the windings. With a vision to change the world one set at a time, we strive to develop the cure for ordinary strings that deliver amazing tone for a truly long time. Strings that stay clean and smooth. Strings that always inspire you to play. Once you experience Elixir® Strings, it's hard to go back to the old way of life. Sure, having to buy fewer sets of strings saves money. 16002 Elixir Acoustic Nanoweb Phosphor Bronze Extra Light Guitar Strings 010-047 String Gauges - 010 014 023 030 039 047 16027 Elixir Acoustic Nanoweb Phosphor Bronze Custom Light Guitar Strings 011-052 String Gauges - 011 015 022 032 042 052 16052 Elixir Acoustic Nanoweb Phosphor Bronze Light Guitar Strings 012-053 Size 16002
