Grey nylon plastic with a subtle metallic sparkle (formerly Alumide.)
About this Product
I would say that this is at least a 99% match to the original. Due to the scale of the item there may be a few things that are slightly not right.
For instance in my image you can see the screw on the right doesn't quite sit flush with the surface like the other screws despite all 3 screw holes being identical.
I have only tested this with White Strong & Flexible.
