Class 15J Bobbins Stamped SINGERGenuine bobbin retail packQty: 10Compatible with Singer models in ranges: 66XX, 72XX, 74XX, 85XX, 99XX or where Class 15J bobbin is specified in the manual.
I can only use 15j bobbins in my singer sewing machine and these worked a treat.
It's great to have a stock of these bobbins for my machine. They are exactly as required, were delivered in good time, and I am really happy with them.
It is very disappointing how many bobbins are sold with no information as to which machine they are for. I have just bought a new Singer which specifies 15J and this is the only pack I found which specifies this model.
