Leak-Free Cork Stopper

HAND CUT CORK FOR MODEL ONE

Produced in small batches by Jacob Bromwell®, this hand-cut cork is crafted exclusively for Model One.

Shaped to original specifications, it restores the precise compression and seal intended in the flask’s design. Over time, natural wear can reduce the integrity of even the finest materials. This replacement cork ensures continued leak-resistant performance while preserving the disciplined proportions of the original stopper. Cut from premium-grade cork and finished for exact fit, it maintains both function and form — without altering the character of the vessel it serves. An original component — renewed. A legacy — maintained.
