Wegen M350 Gypsy Jazz Guitar/Mandolin Pick Thickness 3.5mm
"The cutest of them all! Basically, this is a mini-Gypsyjazzpick, but what a performer. Don't let the dimensions fool you . Great speed, control, volume and sound. A solid winner and Michel's favorite. ( A favorite for many others too!) Dimensions: 27.5 mm long, 23.3 mm wide and 3.5 mm thick. This model also comes in a 2-pack. Look for the orange inserts." -Michel Wegen
