Advantages: • The main advantage of using synthetic v. natural cork is that synthetic cork won't deteriorate over time from water and saliva.
• Synthetic waterkey corks are much easier to install due to their peel-and-stick adhesive backing.
• Synthetic waterkey corks are more forgiving and will allow for more compression than either natural corks or neoprene.
