Richword Black Prewound Bobbins – L Style (SA155)

Description

Richword Black Prewound Bobbins are manufactured using premium 75D/2 (60wt) polyester filament thread to deliver smooth, reliable performance for embroidery applications. Designed for both home and commercial embroidery machines that use L Style (SA155) bobbins, these prewound bobbins help improve efficiency while maintaining consistent stitch quality.

The clear plastic sides make it easy to monitor remaining thread while helping protect the bobbin thread from oil, dust, and humidity. The high-quality polyester thread is soft yet durable, helping reduce friction, static electricity, lint, and thread breakage during embroidery.

Unlike self-wound bobbins, prewound bobbins save time, reduce thread waste, and provide more consistent tension throughout the embroidery process. The 60wt bobbin thread pairs perfectly with standard 40wt embroidery thread, resulting in balanced stitches and professional embroidery results.

Black bobbin thread is commonly used on dark garments and fabrics where white bobbin thread may show through the material. It is an excellent choice for embroidery on black, navy, charcoal, and other dark-colored textiles.

Ideal for logos, apparel, caps, patches, uniforms, and other embroidery projects, Richword Black Prewound Bobbins offer dependable performance for everyday production.
