Cork Stoppers, XXXX Premium Grade

Cork Stoppers - XXXX Premium

XXXX Premium Grade Cork Stoppers function as a closure for bottles, vials, laboratory and other openings. The XXXX Premium Grade has fewer lenticels (crevices) than standard grade. This means they are better suited for use as laboratory corks and for transporting many kinds of liquids. Cork Stoppers 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.
