These are generic replacement bobbins for the Pfaff 1222 and the 1200 series in general.
These generic bobbins work… but not as well as the originals. When you hold the bobbin case by the latch it should hold the bobbin securely within the case itself. These generic bobbins are inexpensive but they tend to fall out of bobbin case as you try to put it back into your machine. This can be super frustrating so be warned! We recommend the originals.
