Four tight, even curves stacked into a form with real attitude, now in plant-based plastic with a bevelled contact edge that keeps every ring crisp. Only the chamfered face touches the clay, so the scallops sit flush against each other without the rib dragging the wall flat between them. The result is a compact, muscular rhythm that you can throw repeatably across a whole shelf of squat, chunky vessels. Press in, pull up, and the rib counts for you. Bold, tactile, and unmistakably handmade.
