• SIZE L FIT - Use only when your manual specifies Size L, Style L, SA155, or Size 9.4 bobbins. Diameter 27/32 in, height 23/64 in. Size A, L, and M are not interchangeable.
• THREAD SPECIFICATION - 40S/2 spun polyester = #60 = approx 34WT; Tex 30, Denier 270. Black thread, about 50 yards per bobbin; match the thread weight to the project.
• BEST USE - SEWING AND QUILTING ON DARK FABRIC with black or matching top thread. 40S/2 is the standard bobbin thread choice for seams, hems, garment work, and quilting where the back can show.
• PLASTIC-SIDED FORMAT - Smooth transparent sides fit front-loading and top/drop-in machines that accept Size L bobbins. For higher yardage in compatible front-loading cases, compare cardboard-sided versions.
• VERIFY BEFORE BUYING - Check your manual or measure an existing bobbin before ordering. This LPB-40S2 pack is made in Malaysia; choose another DOUBLELIN Size if your machine is A or M.
