Three different circular knitting needles of different sizes and composition.  The inner beige one is short and thick (US size 13) and made of wood, whose roughness prevents stitches from slipping off.  The red metal middle one is US size 9, and its tips have been screwed onto the nylon cord.  The outer one is US size 5, nickel-plated hollow brass for speed and unusually long, designed for lace and larger sweaters.
