Continuous filament polyester thread of superior strength in a handy pre-wound style.
A great value on a quality embroidery bobbin thread -- and you don't have to thread a single bobbin! Madeira bobbins are precision-wound with 131 yd/ 120 m of thread. Simply insert one into your bobbin case or top-loading bobbin holder, then thread as normal.
With no sides and no cores, these bobbins work down to the last inch. Economical and convenient. Fine for all machines that accept Class 15 bobbins.
