The original and the best medical adhesive that has been the "industry standard" for over 30 years. It's a little tougher to remove than Beta Bond, but the adhesion is the best all around. Remember; the bond will only ever be as good as the surfaces applied to: be sure to make sure both surfaces are clean, dry and as smooth as possible leaving enough time for the adhesive to tack after application. Witch hazel is excellent for the preparation of surfaces.
