This stopper is ideal for keeping sparkling wines such as cava or champagne for longer. Being airtight helps prevent loss of taste properties. Its screw closure is very easy to handle. Simply turn until the arrow coincides with the open padlock symbol, place the cap on the mouth of the bottle and turn until the arrow coincides with the closed padlock symbol. To be able to remove the cap, it must be turned again towards the open padlock symbol. In addition, its ergonomic design adapts to the fingertips to provide a more comfortable handling and a firm grip.
