*by S***O on 27 December 2025*

I’ve been using this bobbin thread for regular embroidery work and it has performed well. It runs smoothly, maintains consistent tension, and I haven’t experienced any breakage during stitching. Works well with my machine and holds up for ongoing business use. Good quality for the price and I would repurchase.
