Must Read Before Purchase:
-Maintain slower sewing! You might be stuck by the breakage caused by the fast sewing. So our suggestion is to sew slower!
-It would not be suited for fast sewing machines. Polyester thread is more suitable for automatic winding function machine. If you do want to use it on the the sewing machine compatible with a long time, then you should clean up the fluff first.
-Polyester thread is compatible with hand sewing or sewing machine but not the embroidery machines. It is not embroidery thread after all.
-The spools are winded by machines. Sometime it might take some times to find the tails for they are inserted into the threads. If you look closely, you might find out the tail by the trail of the thread.
