Prym Weaving and packing needles are made of hardened steel and suitable for sewing materials such as jute, wool, or linen, and for weaving itself. 

The needle's specially-polished, rounded tips are gentle both when weaving and when sewing the material. Its flattened, curved spear tip can also be used to pierce through thick, hard, and tense material. These needles are used for coarsely sewing sacks, mats or other thickly-woven, firm materials. 

This special tip shape coupled with a cleanly-worked surface and a large, burr-free eye make these needles professional tools for work with coarsely-woven materials.
