Review on 🧵 HONEYSEW Industrial Sewing Machine BOBBINS M Size - 20PCS (#18034) | Top-Quality Thread Spools by Jennifer Roberts

These bobbins work fine but the center hole size is slightly different. I've found that some of them fit a bit looser on the spool shaft for winding, so the hole for the shaft needs to be slightly larger than others sold by long arm manufacturers. They don't fit my bobbin winder that well, so some of them don't wind as fast or as full as other bobbins. After putting them on I found that they made no difference in how they worked in my car and seemed to be doing their job well. The spools also came in a zipped bag and the spools were covered in brownish oil so I had to rub them all very well before using them as the oil was everywhere. I'm not sure I'll try this brand again.
