A paperweight is one of the few desk objects where weight is the entire function, which makes brass a sensible choice: dense, stable and it does not chip. These are plain chamfered bars rather than sculptural forms.
Machined from solid brass and polished, with felt on the underside so they can be slid across a desk without marking it. The pair weighs just over half a kilo, which is ample for a single sheet and about right for holding a sketchbook open.
