These cork trivets are produced from cork oaks which generally grow in Spain and Portugal. Cork is produced from the bark of these long-lived trees which are stripped every 9 years, giving the trees time to regenerate and produce more cork for harvest. This set of square trivets is good for smaller dishes. Protect your table the green way. Set of 3 cork trivets, 7" square. Displayed here with one of our stainless steel bowls.
