The corks I ordered work easily and seal perfectly.

Worked out great

They are not tapered at the top and bottom as shown in pic. And tore with my corker. Would much prefer a non solid cork that are commonly used in wine.

Used this and a hand corker to bottle a sour in Perrier bottles. Took some melted wax, used a knife and sealed the top. Very cool looking and a neat way to cork without spending a ton of money on a floor corker!

These are the ones you need for the small bottles, the 187ml ones. They are too narrow for regular bottles.
