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.
