*Per industry standard, length is measured from the bottom of the frosted joint to the tip of the downstem — not the overall end-to-end length of the piece. However, Human Grade measures the entire length of the downstem. Please subtract 1 inch from the overall stated length to get the industry standard measurement. See our Downstem Measuring Guide for details.*
