The Universal Ruler Tool - Fits in Every Wallet!
With the Kirstein ruler tool for string instruments, you always have full control over the string action of your instrument. Whether guitar, bass, ukulele, banjo... this handy card is suitable for any string instrument and can be carried in any wallet thanks to its credit card format, even when you're on the go. All scales and markings are given in both millimeters and inches. The vertical scales allow easy measurement of the depth of nut slots and fret slots or the height of pickups.
