The ideal bobbin for domestic machines, Clear-Glide bobbins are wound on a plastic-sided bobbin shell. Because of this, they are not affected by humidity or oils. They are responsive to machine thread sensors so you don't have to worry about your yardage.

Clear-Glide offers more stitches and yards per bobbin than both competitive and machine-wound bobbins. 

Conveniently packaged in a bulk box of 144, these ready-to-use bobbins eliminate the need for manual winding, saving time and increasing efficiency.

144 Bobbins. 115 yards per bobbin. Class 15/A. Black.
