These high quality synthetic corks will maintain their elasticity and seal for up to 4 years. Supercorks make a great alternative to cheaper natural corks that may have issues with porosity or TCA contamination if used for an extended period of time. Cork measure 23mm D x 43 mm H.
A floor corker is recommended to easily insert the cork. They require 48 - 55 lbs of force to remove them from the bottle, depending on the diameter of the bottle mouth. Using a wine key or other levered cork screw is suggested.
