Band width = 3.7 cm width of buckle = 4.7 cm. Solid simple black belt - well individually just to fix so just required by clamping holes instead how the expanse. Ideal supplement to carnival costume or SWAT Police or outdoor activities. For fancier occasions less suitable as simple plastic optics. Very good value for money. There seem to be several versions. The belt obtained is black on both sides although description bicolor. Never mind - I do not even prefer that.
