Stoppers Cork, Hillman, 1-5/16 in Top Diameter

Cork is an impermeable, buoyant material comprised of bark tissue that has been harvested and refined for commercial use. The extra large-sized cork stoppers have a tapered shape to provide a secure seal in various sized containers. The natural cork construction can be cut to an exact length and its natural elasticity helps form a tight seal. Commonly used as bottle stoppers.
