Vantr never holds the physical asset in its possession.  The physical asset that is minted as NFT (via digital twinning), will remain in possession of the owner of the NFT.  The owner needs to ship it to the buyer directly after the sale.   It is advised that the owner inform the buyer to insure the shipment to the desired value.  Typically the shipping and insurance cost is paid by the buyer.  However, the seller can choose to bare those expenses.
