Engrave with a special message she will cherish forever. Please review the photos and follow this simple method to measure for proper fit: Make a fist and measure the length from the outside of the first knuckle to the point between the third and fourth knuckle. This measurement should equal no more than 2 3/8 inches for the 7 1/2 inch bracelet; 2 1/2 inches for the 8 inch bracelet; 70mm or 2 3/4 inch for the 8 1/2 inch bracelet. When in doubt, go a little larger to be safe. With regard to engraving options: Front is the outside. Back is the inside.
