One Twist Locks It, One Twist Opens It

Twist-lock seal
Turn the dial clockwise and the stopper locks into the neck. Turn it anticlockwise and the seal releases so you can lift it out. The icons on the dome show the current state, so you never have to guess.

Fits sparkling and still
The stopper is made for inner neck diameters of 18-23mm, which covers the standard champagne and still wine bottles in the lineup. Measure the inside of the neck before you order, since a bottle outside that range will not seal. The same check applies across the champagne stopper range.

Compact black dome
The matte black dome measures 39 by 39 by 32 mm and weighs about 18 g. Side grip recesses give your fingers a firm hold, even when your hands are damp from a chilled bottle. The soft-finish surface wipes clean with one pass of a cloth.

Seal a Bottle in Three Turns
- 1Unlock first
Turn the dial anticlockwise until it sits on the unlock icon so the stopper slides freely.
- 2Insert firmly
Push the dome straight into the bottle neck and keep it square so the top sits flush.
- 3Lock it
Turn the dial clockwise until the lock indicator shows locked. To open, turn it back to unlocked before lifting it out.
From Flat Leftovers to a Sealed Pour

The Bottle That Went Flat
The cork goes back in, and by morning it has worked loose. Bubbles thin out and the wine tastes tired, so a bottle you paid for ends up in the sink. Pushing the old cork harder is not a fix.

One Twist, Sealed
Push the dome straight into the neck, then turn the dial until the lock icon shows. The grip recesses on the sides give your fingers a firm hold, so sealing takes seconds.

The Pour Tomorrow
Next evening you turn the dial back to unlocked, lift the stopper, and pour. The wine still has life in it, with no dull edge from a bottle left open overnight. Keep one beside your wine bottle opener so the bar cart covers both ends of the night.
Keep the Seal Clean
- Rinse after each use
Warm water clears wine residue from the silicone seal.
- Dry it fully
Let it air dry before storing so the seal stays clean.
- Clear the residue
Leftover wine left on the silicone can carry over to the next bottle.

Questions and answers
The stopper is made for inner neck diameters of 18-23mm. Measure the inside of the neck, not the outside lip, and compare it to that range before you buy. A neck outside the range will not seal.
Yes. The lock works the same on prosecco as on a red. The packaging shows it fitted to sparkling, rose, red and white bottle necks.
The main materials are ABS and food-grade silicone. Rinse it with warm water after each use, dry it fully, and store it dry.
The listing claims 7 days of freshness. Results depend on the wine, the bottle and how cold you keep it, so treat the stopper as a tight seal, not a guarantee. Keep the bottle upright in the fridge and pour within a day or two for the best taste.
A pump needs repeated pumping and can lose its seal over time. The original cork loosens once it has been pulled. This one needs no pumping, and the lock icon shows at a glance whether it is sealed. It is a one-time purchase, so each saved bottle costs you only the stopper.
