Collar vacuum cork from Stelton is a smart and stylish solution for preserving the freshness of your drinks longer. Designed by Daniel Debiasi and Federico Sandri, the cork uses a built-in pump function that effectively removes air from the bottle and slows oxidation so wine stays good for several days after opening. It also works as a regular closure for carbonated drinks — perfect for keeping the bubbles. Made of stainless steel with a Teflon®/brass coating — practical, easy to use, and a small everyday pleasure to have in the kitchen.
