This is the new and hard to find The Expanse Epstein Yacht Die-Cast Vehicle by Master Replicas. The ships in The Expanse rely on an Epstein drive to reach the kinds of speed that make interplanetary travel practical. The drive was first tested on a second-hand yacht, and was discovered almost by accident. The Yacht is 6 inches (16 cm) in length. Comes new in a manufacturer sealed box.
