Tulip is a world leader in needle making. The key attributes of Tulip needles are: (i) the extruding process produces the thickness/thinness ideal for the needle's application; (ii) easy-to-thread needle eye; (iii) the hardening and tempering process produces needles with a superior hardness and elasticity; and (v) the lengthwise polishing process minimises the needles contact with fabric.
