OP, unfortunately the carriers involved in eIP or the GSP (eBay International Shipping Program or Global Shipping Program) will deem some items to be banned items, even if they’re not. There is no arguing with them. They’ll simply not deliver the item.

Some items that have fallen into this abyss of non-delivery include butter knives, a drum, anything that might once have contained fuel (even if it’s empty and clean now)…
