I just received this set. Upon removing it from its carton I could readily see that the cord is well made. It will last a long time. It has 10 sockets and a carton of 12 bulbs is included; yes, 12. I am going to use this with 10 paper lanterns. The included bulbs, at just 11w each, may not be bright enough for my particular need so I think I'll use LED bulbs rated 25w with more illumination, instead.
Each socket has a molded-in loop for hanging on a guide wire with an S-hook
Two incandescent spare bulbs included (12, total)
