Collar Vacuum Cork, brass

This is a smart bottle stopper with a vacuum pump that belongs to the popular series Collar from Stelton. The vacuum stopper has a built-in pump function that prevents the wine from being oxidized after the bottle is opened, and can preserve the bubbles in, for example, cava or champagne. Should be cleaned with lukewarm water and mild dish soap, but without a brush as it can scratch the surface.
