Clover-Microtex Needles. The Microtex needle has a very sharp, acute point. It is ideal for sewing on fine wovens or any other application where it is important to pierce the fabrics. This prevents puckering on delicate fabrics. It was developed for the modern micro-fibers, polyesters and high thread count, high quality fabrics. This package contains two size 60/8 needles, two 70.10 needles and one 80/12 needle. Imported.
