Quality of my embroidery has diminished since starting.to use these bobbins

GREAT WAY TO SAVE!

These are the best thing ever for the sewer. So economical, thread is much tighter, therefore, more on the spool than I could ever wind, and no time involved. I would recommend for anyone who sews, get these, you will never be without them. I know I won't.

Great quality and have not had any bobbin problems.

This is pretty much the best thing I bought all last year. I run an online shop selling handmade baby bibs and go through plain white bobbins like crazy. I was getting so sick of wasting time and energy winding bobbins and dreaded doing it so I bought these....and I WILL NEVER GO BACK! It is so wonderful to just reach into the box and grab a new bobbin when I need one. I did the math and this box probably saved me 5-6 hours of my time over the past 6 months or so. I have NEVER had a single problem with these bobbins.
