Your guests are going home but you still have a bit of that fine wine left? That's when our Wine Preserving Pump comes handy! This pump preserves wine like no other, preventing oxidation and high pressure changes within the bottle for up to one week. The stoppers are also horizontally leak-proof! Simply place the stopper on the bottle and the pump on the stopper. Pump until the white indicator on the stopper stays down. Get pumped: a wine lovers' accessory with an original Trudeau Design is in town!
