Product Features

Instructions for use:
- SERAFLEx should be used as both needle and bobbin thread.
- Thread tension should only be “as tight as necessary”, meaning as loose as possible.
- The bobbin thread should also be wound with as little thread tension as possible to prevent the thread from stretching beforehand.

The sewing thread is suitable for the sewing machine.
