Vibrant and colorful, HUGE BreakDown bobbins! Lightweight, solidly constructed, eye-catching bobbins of aluminum, acetal (Delrin), and beautifully finished laser-cut acrylic (Plexiglass). Attractive, strong, rigid, and durable. Incredibly convenient for travel and storage.
Assembly: Hold the bobbin end by the outside perimeter, then insert the bobbin core and twist about 1/4 turn as you gentlypress the core into the bobbin end. It's like pushing a cork into a bottle; it doesn't take a lot of force, but you MUST twist a small amount during assembly. Be sure that the bobbin core is fully seated and the shoulder at the end is tight against the bobbin end.
Disassembly: Hold the bobbin end and gentlypull on the bobbin core while twisting the core about 1/4 turn. Easy!
NOTE: Acrylic bobbin ends are shipped with a protective paper covering. Peel this off prior to using the bobbins!
