If it is the Capodimonti figure, you are already showing your lack of experience with UK postage, quoting for a method of postage suitable for items up to £20 in value. You need Special Delivery.
As far as posting to Italy I suggest you decline. Using proper methods of postage it would be very expensive, risk of breakage very high and Italian Post is not the best in the world.
You would be risking a lot of money on loss or damage or fake claims of not as described, with no guarantee that you would be able to make a claim on Royal Mail.
There is also the new Taxes to consider in the EU. I don't understand the rules so best to not get involved.
