When I say "fit" I mean the notch in the bobbin works on the notch on the bobbin spindle. As you can probably tell from the picture the bobbin with multiple holes has a longer notch then the bobbin with 1 circular hole. The notch on the bobbin with the 1 circular hole is deeper than the bobbin with the multiple holes as well.
