Aglica corks were developed for the wine industry to address inconsistency, oxidation and leakage. These corks are made in France from Suberin (the purest part of cork) and that is blended with a proprietary polymer to enhance the natural elasticity and sealing properties of cork while maintaining a natural appearance. Do not use these corks with plastic plunger or hand lever type corkers. Use a floor corker for best results. The size is #9 x 1 3/4".
