Postage costs depend on the weight of packages.
For small weights like jewellry / fittings / fabrics / etc. the price will be 6-12-15-…€.
If speaking about body armor, the weight of a package (your order) depends on:
Your size. This is why I first ask for your measurements in your underarmor cloths sending the measurement chart while discussing the order.
The whole set of your armor (spaulders / tassets may be included).
The sort of steel (par example, the hardened spring steel armor will weight about 20% lighter than mild steel).
The destination (sending to USA / Europe / British Isles / Australia / Asia cost not the same of course).
Average weight of the cuirass is about 8-9 kg.
Speaking about helmets/braces/greaves/equipment/etc., the weight of course will be less. The average helmet with chainmail aventail weights about 4-5 kg – so the postage cost will be about 30-35€ (to Germany par example).
Remember that this is the international mail. Prices surely differ from your local. But anyhow Russian Post is not too expensive. These prices of course include the tracking of your parcels. If you will need the Postal insurance, we have to discuss this personaly.
Europe / Frankish / Byzantine
Price is for helmet rised from one piece of steel.
