Suggested retail price. In-store prices and availability may vary by location.

Compressed cork, so the face reads as a fine even mosaic of granules rather than a single grain, and it takes a clean flat top. Being tapered, it wedges into a neck rather than having to match one exactly, which makes it forgiving on thrown and hand-built work where no two necks come out quite the same. Measure your neck across the inside of the rim and take the cork whose bottom diameter is a shade over it.
