The belt is made of leather. Metal parts are made of brass.
How to choose your size?
Put on clothes, what you want to wear the belt over. Take another belt, tighten comfortly and mark its buckle position. Put it off, lay it flat and measure the marked lenght. Let it assume you got 116 cm (45 ½ in.). Look to the chart below: 116 cm is in the gap 98-124 cm for belt size 140. You should take this size. Better if your around measurement is clother to end of the gap, but not straight in the end.
1 inch = 2.54 cm.
