The total weight of the gold including all the objects is more than one kilogram. There are thirteen gold appliques for horse halters with images of human, animals and plants - objects which are rare in Thracian archaeology. Another two rectangular objects are golden with figures of standing warriors, used as a decoration for the sword sheath. There is a massive circular decoration for the King's armour.
