Screw Top Corks

A SMALL COMPONENT. AN ESSENTIAL STANDARD. Produced in small batches to original specifications, these replacement corks are crafted exclusively for our matte stainless steel, pewter, and copper screw-top flasks. Over time, natural compression and use can diminish seal integrity. This set restores the precise fit and leak-resistant performance intended in the original design — preserving both function and form. Each set includes four cork stoppers: two sized for copper and stainless steel screw-top flasks, and two sized for pewter screw-top flasks. Cut from premium-grade cork and shaped for exact proportion, every stopper ensures a secure seal while maintaining the disciplined silhouette of the flask.
