ChiaoGoo's Premium Bamboo Circular Knitting Needles have smooth joins and clear nylon cables. The joins are made from nickel-plated copper, and they swivel! The needle sizes are laser engraved onto the sizes of the needles, so they won't wear off.
 
The bamboo these needles are made from is special, it is Chinese Moso bamboo, which is known to be one of the strongest bamboo species in the world. It is warm to the touch and smooth for easy knitting. The points on these needles have been handcrafted by highly skilled Westing Bridge craftsmen.
