For an accurate sizing job, you need an accurate finger measurement. What could be more precise than the exact inside diameter and circumference in mm? Each ring in our 4-Scale Finger Gauge is marked with:

• Inside diameter in millimeters, 13.0 to 24.2

• Circumference in millimeters, 41 to 76

• Closest American equivalents, sizes 1 to 15-1/2

• French sizes 1 to 36

• Meets ISO Standard 8653.

Bright chrome-plated 2mm wide bands. One-piece construction (no soldered seams) means this Finger Gauge is consistently accurate and won't break or distort even after years of use. Imported.
