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.

WHY IT EXISTS

Permanence Requires Renewal.

Because heirlooms are maintained — not replaced.

These cork replacements exist to preserve seal integrity, protect finish, and extend the life of the flask without altering its design.

Serviceable by intention.
Enduring by design.

HAND-CUT FOR COPPER SCREW TOPS

Produced in small batches, these cork stoppers are cut specifically to fit Jacob Bromwell® copper screw tops. Formed for proper compression and alignment, they maintain a secure and balanced seal. Made to fit. Made to function.

DESIGNED FOR REGULAR USE

For those who carry their flask consistently, proper maintenance matters. A well-fitted cork preserves both performance and presentation — ensuring the flask continues to serve as intended. A simple component. An essential detail.

BUILT FOR THE MOMENTS THAT COUNT

Given, carried, and kept — through milestones that define a life well lived.
