ChiaoGoo Dark Patina Bamboo DPN - 6 Inch

I have broken 2 of these knitting needles. The size 1 was my fault but just knitting along and a size 2 just broke right where the size was stamped in it. I think the stamping weakens them. As far as the needles themselves I like them better than other bamboo needles. I under stand why there are 6 needles to a set.
