This flexible pick holder uses a patented twist-lock design to mount on the strings of any guitar just above the neck. * Place the holder between the strings and rotate it 90 degrees, picks are then held in either of the 2 wedge shaped slots. * Wedgies use no adhesives and will not damage your guitar in any way. * Wedgies will not affect tuning or tone * No more stick-ons or weaving your pick in the strings, just put a Wedgie on your guitar and stop losing picks.
