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.

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 your copper screw top.

Made in small batches, our cork stoppers are made exclusively for all Jacob Bromwell® flask screw tops.

For those who rely on their flask.

If you rely on your flask regularly, you know how important it is to keep your flask looking beautiful and leak-free.

SEE THE CRAFT COME TO LIFE

From raw metal to finished heirloom — nothing is rushed.
