Please;

  • Measure your ring size at the end of the day when fingers are at their largest.
  • The Sizer must fit comfortably, snug enough so that so that it will not fall off, but loose enough to slide over your knuckle.
  • Do not measure your hands when they are cold, they may have shrunk up to half a size.
