I know how fragile cast iron is. I use newspaper for small items, and packing peanuts only for very light items. I use a variety of bubble wrap and peanut-packs for most mid-size items. Heavy items will be packaged using solid styrofoam block. It is very rare for the items I pack to be broken, as my feedback should attest.
Especially on those large items. I can be flexible with scheduling - just ask! The item "Thermo Scientific Cimarec SP88850105 hot plate & magnetic stirrer" is in sale since Tuesday, October 9, 2018.
