Items are generally wrapped in multiple layers of bubblewrap and placed in strong double-wall cardboard boxes with the void filled with a 100% recycled polystyrene loosefill. I have tried alternatives to bubblewrap but none come close in terms of the level of protection they provide. They are not the cheapest, but do offer a professional, fast (normally next-day) service and have proper shelving in their vans, which many of their competitors are unable to provide.
If at all possible, please re-use the packaging, or find someone that can. The item "Antique transit theodolite, William Stanley of London, immense proportions" is in sale since Friday, September 13, 2019. This item is in the category "Collectables\Scientific Collectables\Engineering & Surveying".
