The strap looks like a good old solid leather strap. The buckle is a fine "zinc alloy" from China. I just can't understand why anyone would make things like screws and tools. And belt buckles, zinc. Zinc is soft and brittle, so it breaks, bends and loses its surface very easily like this belt buckle. Less than a year later, the crossbar holding the pen broke off, rendering it unusable. Due to the way it is sewn onto the strap, you cannot change the buckle without undoing the stitching. There's also a screw holding it in place, which is also likely zinc and will come loose if you try to pull it out. I would definitely give the belt 5 stars if the buckle wasn't rubbish. I wish someone would do something these days that doesn't need to go to the landfill ASAP to make you spend more money. I'm really tired of disposable items that shouldn't be disposable.
