Martin have finally updated their string packaging. The old style cardboard box is gone and like many other brands they have adopted a sealed pack to stop corrosion. They have also dropped the confusing 'two strings in an envelope' and each string now comes in its own envelope. 

The new packaging is starting to arrive now in some Martin lines.
Martin has also changed some of their strings range. For example FX is no longer available in Bronze. You'll see the full up-to-date range at www.martinguitar.com
