ChiaoGoo bamboo needles are made of Moso bamboo, the largest and strongest bamboo in the world. Our craftsmanship is the result of over 100 years of experience passed down by generations of skilled craftsmen. Due to the quick, renewable nature of bamboo, we are proud that the products we offer are eco-friendly. Our stainless steel products are made of surgical-grade, stainless steel that is hypoallergenic and, in most cases, not reactive to sensitive skin. They have a nice smooth, satin sheen that won’t reflect any light making it hard to see your work. They are lightweight and strong! The needle is precisely machined resulting in perfect tips and joins. We don't carry all the range In-Stock, so please ask if you are after something ASAP. If we don't have listed you're needing, also ask and we'll get it in for you.
