Flat Shank Light Ball Point These needles were developed for use in the Brother Professional 6 Needle Machines (PR600, PR 600 II, PR620, PR650) and the Babylock Professional 6 Needle Embroidery Machines (EMP6, BMP8, BMP9). They also work in the new Brother Pr1000 and Baby Lock ENT10 machines. Although they are flat shank needles, they are built to industrial standards with a reinforced blade, oversize eye and a light ball point. Both Brother and Babylock recommend using these needles to insure that your embroidery machine works correctly.
