From This Might Be A Wiki
TMBG is going into the guitar string business, if only on a limited scale. "Lefty Strings," cosmetically altered to appeal to lefty guitarists (like our own Mr. Flansburgh,) are available in a Lefty Guitar Starter Kit (two packs of strings and three custom Flans picks) for just $10. They are packaged beautifully, with drawings by Flansburgh, and are made from top, professional quality steel and nickel in standard gauge (10-46mm). As good a souvenir as they are a working musician's tool. Plans to introduce "Girlie" strings "the strings for girls" and "Cyclops" bass strings "the strings for one-eyed bass players" are in the works.
