This is a handmade brass buckle called “Guardians”.
The buckle has a border post with Ukrainian trident together with its guard. A lion with a golden crown and a Cossack with a musket. The buckle's outside serves as a picture of the fortress walls. This belt is to honor all who stand on guard of Ukraine's borders and independence.
The buckles are cast from brass. After casting, each buckle is processed manually.
