semi-elaborated natural cork stoppers and colmated natural cork stoppers at the definitive dimensions stage, and
finished natural cork stoppers and colmated natural cork stoppers ready to use.
It describes the anomalies of cork stoppers that can be detected by visual examination of the manufacturer or the end-user.
