Please note that 16x231 refers to the system, or type of needle; size (diameter) is denoted by the suffix. For example, 16x231-9 is the smallest, or thinnest size we offer in this brand; 16x231-23 is the largest, or thickest size. The eye of the needle increases with the thickness to allow for sewing heavier threads.
