Vintner's Harvest VHC Colmate Corks 38x24mm.
The Colmated (Bellcork) is one of the most popular corks. The Colmated wine cork is made of natural cork and then treated with a colmated process to fill the outer imperfections of the cork. This process combined with the surface treatment gives the Colmated cork improved sealing ability. Recommended for storage up to 2 years.
