XXX Standard Grade Cork Stoppers function as a closure for bottles, vials and other openings. The XXX Standard Grade has a few more lenticels (crevices) than a XXXX Premium Grade. This means they are better suited for packaging dry goods and standing liquids. If using corks to transport many kinds of liquids or for laboratory environments, consider a XXXX Premium Grade as the fewer lenticels will provide a better seal. Cork Stoppers are also an excellent masking devise for covering holes when painting and are safe to 300 degrees F (150 C). Many sizes are available to plug openings from 1/8" up to 2". All our Cork Stoppers are made from 100% natural cork. Buy online today!
