Here is a simple little pen model that I made this afternoon. The model is fairly low-poly, but is nicely detailed. The materials are all procedural. The materials are set up in such a way as to facilitate fairly quick render times. This should be perfect to fill out a scene with some added detail. PLEASE NOTE I have not included any of the HDRs that were used to render the sample image. You will need to use your own HDRs in order to achieve nice reflections.
