Review on 🧵 Efficient Sewing Kit: Paxcoo 72 Pcs Bobbins and Sewing Thread Set with Case for Brother Singer Babylock Janome (Assorted Colors) by Jessica Lewis

Nowhere in the information is it stated that these reels are CLASS 15 and NOT CLASS 15J. I still had to get covers (as well as a 60 inch tape measure and pins) but I pulled my hair out trying to figure out why my machine (Singer 7258) was skipping zigzag stitches. I googled CLASS 15 and CLASS 15J and found that using flat (class 15) bobbins on my machine results in skipped stitches. Class 15J is convex. That moment ah-ha. If only they'd stated it was class 15 I could have avoided a lot of trouble. But I have boxes and I will buy Class 15J roles to fill them in. Write it down to gain experience and move on. If you want class 15 coils this is a GREAT BUY.
