These self-threading needles, also called blind needles, have a special open and springy eye. They are relatively easy to thread, since you only need to insert the stretched thread through both eyes and thereby hold the thread. As a result, even people with visual impairments have no problem threading. In addition to this special, golden, and burr-free eye, you will recognise the known quality parameter of a classic hand sewing needle in this needle, along with the even, non-porous, surface for slippage, the attuned spring stiffness, and the long and exceptionally slim-polished tip shape. Prym offers the self-threading needles, also known as blind needles, in assortment packaging of 6 units each in sizes no. 5 to 9.
