Let’s Bottle It Up!

The Balloon Plug is a great bottle cap that is versatile enough to fit any bottle. It has a very special way of sealing the neck and opens only when you release the special valve. Take a look at the renders to see how beautifully it works and can be adapted to different caliber bottles.
