These self-threading needles have a special open and flexible eye. They are relatively easy to thread, since you only need to slide the stretched thread through the opening in the upper eye which then holds the thread. As a result, even people with visual impairments have no problem threading. In addition to this special, burr-free eye, you will recognize the known quality parameters of a classic hand sewing needle, namely the even, non-porous surface for easy gliding, the attuned spring stiffness, and the long and exceptionally slim, polished tip shape.
