A value 125-piece pack of Class 15 plastic bobbins—the most common bobbin style for many Japanese-design machines. Stock up for classes, studios and frequent colour changes across garments, quilting and crafts. Fits many Brother, Riccar, Singer, Janome, Kenmore, White and Baby Lock models; not compatible with Pfaff, Elna, Husqvarna or Bernina. Durable clear plastic keeps thread visible at a glance to reduce mid-seam runouts and mix-ups.
