Review on 🧵 200 Pack Transparent Class 15 Plastic Sewing Bobbins for Juki Brother Baby Lock Singer Viking Pfaff, Size A, SA15 by Gelin Battle

I bought these bobbins for my Juki HZLlb5100 sewing machine. Which I thought was a good buy. NO IT WAS NOT! . The spools have a plastic ridge on the inside in the middle. Where the filament winds up if I were to use these spools my filament wouldn't wind up properly for 1. And I would share the thread, I'll wrap them up and send them back the next day. I later contacted Switch & Vac Direct, where I bought a sewing machine. And I was told that these previous bobbins are not suitable for my sewing machine. Although that fits the list juki, I would ruin my new machine with those old bobbins. If I would start sewing. The spool was not spinning properly, causing an error with the motherboard. If you have a computer controlled machine, you have purchased Juki Pacific brand bobbins for your machine.
