A bottle plug that expands when you push the lever down. The silicone body swells against the inside of the neck and holds an airtight seal, so an opened bottle keeps its flavour instead of going flat and dull overnight.
Lift the lever and it releases just as easily. Because the seal is mechanical rather than a friction fit, it goes back into a bottle neck a natural cork would no longer fit.

Single stopper
Fits most wine bottle necks, and works on oil, soy sauce and vinegar bottles too
Not recommended for champagne or carbonated drinks: rising pressure can push the plug out. Do not shake a sealed bottle, and stand it upright after fitting.
