It's the one cork that rules them all. The Haley's Corker 5-in-1 Tool aerates, filters, pours, corks, and stops wine, oil, vinegar or any liquid. The Corker simply screws into any bottle opening. A flip-away cap seals the bottle. The filter and aerator are built into the Corker base. Fits any bottle with a standard wine bottle-sized opening. Made of durable FDA approved BPA-free plastic.
