A marvel of mechanical elegance and functional art. Precision-cut from rich Baltic Birch and capped with crystal-clear acrylic, each Nexus Coaster is a self-contained kinetic sculpture. Its true potential is unlocked when joined with others; the interlocking design allows you to create an ever-changing tableau on your tabletop. The turn of one sets the entire array into a mesmerizing, synchronized dance. It is more than a coaster; it is an intelligent conversation starter , a bespoke statement piece , and an unforgettable gift for a person who appreciates things that are beautifully clever.
