No angeled or deformed corks. Very small chips and lateral worm activity in the middle of the body of the cork may be acceptable. These are corks of average visual appearance with one or more major visual flaws which will be of cosmetic nature only. Thus they may be aesthetically unappealing, but functional. Lenticels and horizontal cracks on body may open up when ends of the corks are bent.
Large chips are acceptable.
There may be heavy, but not continuous porosity.
