Superior quality 304 Stainless steel head ball pins. Hypoallergenic Qty: 8g (approx 48- 50pc) Size: 70mm Gauge: 21g (0.7mm) Ball Head: 2mm Note on stainless steel: It is inaccurate that stainless steel should always be “non-magnetic”, including austenitic grades. Sheet and coil start as non-magnetic; however, once the material is worked via polishing, cold rolling & cold forming it creates a level of magnetism. This can be verified via online research. Sodacraft carries only high quality, geniune Stainless steel. Our products are often polished or cold worked which may lead to a slightly magnetic finding.
