Likewise, Shein’s Rocktubes are made from the same material as his necklaces — laser-cut Plexiglas in a jumble of colors and glittery hues — but the idea behind them is much more abstract. “They were certainly an exercise in color and form,” says Shein, “and graphically they do look like a slice of rock. But a rock to me is a fairly cosmic, wondrous object, and tubes are interesting as well. Basically it’s a thing that allows something to pass through, but it’s also the thing that’s passing through. It’s the container and that which is contained. Does that make sense?”
