Cork Stoppers
Compressed for a fine texture, cork stoppers are breathable container closures that do not compromise the protection of contents. Resistant to pressure, the devices will not pop off even with interior gas built up. Easily cut the environmentally friendly alternative with a metal borer to insert glass tubing. Although choosing the correct diameter size is still important, the raw material of cork stoppers has a natural ability to adapt to the opening shape for a leak-proof seal.
