ChiaoGoo needles are made of Moso bamboo, the largest and strongest bamboo in the world. These needles are a high quality yet very attractively value priced when compared to other brands on the market. The coloring is a warm brown and is completely natural. No dyes or stains are used to achieve the warm brown shade. Some consumers appreciate the color as it provides contrast with the majority of shades of yarn. Vendor's MAP agreements states the pricing cannont be advertised on line at a discounted price. It must be listed at MSRP. ChaioGoo circulars feature silver ferrel and clear flexible cable. The cable itself spins within the ferrel which is a nice feature as the cables do not twist as you knit. The connection between ferrel and cable is smooth.
