That dramatic double-sphere silhouette, with its tight central pinch and two full swelling chambers, now in plant-based plastic with a bevelled contact edge. Because only the chamfered face touches the spinning wall, the deep concave curve transfers cleanly into the clay without the rib catching or chattering on the way in. Press it firmly against the outer wall and the form does itself in a single confident pull. Perfect for decorative vases and sake bottles where volume and drama are the whole point. Two bubbles, one motion, even less guesswork.

How to use
Designed for gripThe cut-out holes are for your fingers. Hook a finger or thumb through one or two of them for a secure hold, even when your hands are slick with slip.
Find the right angleHold the rib at a low angle against the clay and let the shaped edge do the work. Light, steady pressure smooths walls and pulls profiles into shape without gouging.
Rinse and goRinse off slip and clay residue under the tap and wipe dry. A soft brush helps lift dried clay out of the finger holes.
Cool water onlyStick to cool or lukewarm water. Hot water and dishwashers can soften the material and dull the profile over time.
Store out of direct sunlightKeep ribs in your tool drawer or a shaded shelf. Prolonged UV exposure can slowly weaken plant-based plastic.
Treat the edge gentlyThe shaped edge is what does the work. Avoid dropping the rib onto hard surfaces or stacking heavy tools on top of it — a chipped edge will leave streaks on your pots.
