there's a small element that is used to cut the capsule surrounding the plug (sorry I'm no expert ^^)
it's clean, it's well done and very simple.
Next comes the opening of the bottle itself.
It's just magical, it surrounds the bottle with the handle of the bottom, it was well in hand? perfect, we take the second wrist is folded completely to the screw completely fit into the bottle, the handle is returned to the original position and bam, it's open.
Vacuum is made the same manipulation to remove the cap and it's over.
5 seconds you opened your bottle with class.
a beautiful cap is also provided.
Packaging is ultra classy, too, suddenly, I feel compelled to put it back in !!!
the downside if any is that the device is a bit too bulky, do not expect the store with forks and knives.
