These are completely useless, two don't even go into the bobbin winder of my Vintage 201 singer, the rest cant be wound on the machine because the hole that allows the bobbin winder to hold the bobbin is drilled in the wrong location. When I compared them to the good ones i have, the height is also wrong. I think I may look for a hardware store to drill a new hole for me but they might still not work since the height is wrong. Just a waste of money, don't buy it.
Item did not arrive and I was not refunded
