The most important factor that determines how something should be packed is what material the part is made out of. Soft metals (copper, brass, and zinc) should be packed with more care. A minimum of 2 layers of bubble wrap (3/16” standard small bubble) is needed no matter the size of the part.- “Use Best Judgement” but minimally these small parts need to be put in individual poly bags. Zip Lock sandwich bags are not an acceptable substitute for poly bags.
