This is the most efficient stopper on the market.
Shaped like the corks used for thousands of years it fits all variety of bottles. It fits screw-top bottles that the tapered style with 3 o-rings does not fit. As you can see in the picture, 2 o-rings of this stopper make contact with the inside of the bottle to form a tighter seal, while only 1 o-ring seals with the tapered stoppers. With a little twist putting it in the bottle, it creates a beautiful friction fit.
It stands so can be displayed on a shelf when not in use. It is heavier and more balanced.
It has an 8-32 (screw size) stud 3/8″ high. This is the size of all cabinet knobs (see picture) and a few of the decorative knobs Hobby Lobby sells. Wood, ceramic and pottery even golf balls can be used with this style.
