Black nylon plastic with a matte finish and slight grainy feel.
About this Product
The buckle combination of a steel frame and a plastic face is way cheaper than a solid steel buckle. This plastic buckle face/cover slides right over the steel buckle frame I also sell.
The cover clamps to the frame with a #6 - 1/2" countersunk set screw.
The Strong & Flexible polymer works well.
You can highlight the letters with a Sharpie Silver marking pen - or paint it.
