The Story
After years of use, you may need to replace the original copper screw-top that came with your copper flask. 

Keep your Jacob Bromwell® copper flask looking as sharp as possible, or keep a few on hand as spare parts—which is especially useful if you travel with your flask. No matter the circumstances, we've got your covered. The solid weight and build quality is readily apparent, with each one being precision machined to aerospace quality standards and built from 22 gauge solid copper. It ships to you with our proprietary SuperPolish™ finish and our iconic diamond-pattern knurling to provide an easy grip.


Imperfectly Perfect: Minor imperfections lend charm, depth, and individuality to each piece and are a natural part of the 100% handmade process. Embrace the imperfect. This is the Jacob Bromwell® way.

Aerospace quality, precision machined screw top.

Our aerospace quality, precision machined copper screw top which guarantees a 100% leak-free flask every time you fill it. Twist, sip, enjoy.

Machined Screw Top (Copper)
