I sold a set of CPIs on here and shipped them. I wrapped the pipes and stingers themselves in saran wrap, and then put some thinner house insulation in the bottom of the box, then a pipe, more insulation ect... It didnt weight much at all and worked very well. I really try hard to package stuff up nice becuase Ive gotten some stuff that was boxed up kinda shitty before and it sucks ass.
