Attention all sewing and embroidery enthusiasts! This New brothread bobbin thread set is exactly what you need for smooth, professional results. You get two huge spools - one black and one white - each with a massive 5000 meters (that's 5500 yards!) of high-tenacity polyester filament thread. The 60WT thickness is perfect for using as bottom thread in your embroidery projects, giving you consistent tension from start to finish without breaking. What's really cool is that New brothread has been in the business since 1988 and uses Italian twisting machines and German winding technology, so you know you're getting quality stuff. This thread works with most sewing and embroidery machines that use Size A bobbins (that's the 11.4mm height ones). It's super economical too - these giant spools will last you through tons of projects without needing constant replacements. The basic black and white colors cover most of your needs, and if you want to wind your own bobbins, you can grab their blank bobbins and plastic case separately. Whether you're working on DIY embroidery, professional projects, or just regular sewing, this reliable bobbin thread won't let you down. No more running out of thread halfway through important projects - with 5000 meters per spool, you're set for the long haul!
