Never worry about getting the wrong ring size!
 
Easy as slip, zip and read off! The ring sizer tool works like a belt. Push the end through the buckle to form a ring shape. Slip the ring sizer onto your finger. Adjust to give a comfortable tight fit and check if able to slip back over your knuckle. When the best fitting is achieved, read off the indicated size number by the arrow.
