Flask Cleaning Brush Set

PRESERVES A LEGACY

Designed specifically for the interior proportions of your flask, this three-piece brush set ensures thorough cleaning without compromising finish or structure.

Each brush is calibrated for reach, flexibility, and controlled stiffness — allowing it to navigate curves and narrow openings while safely removing residue from within. The bristles are firm enough for effective cleaning, yet gentle enough to preserve the integrity of the metal. Constructed for repeated use, the set reflects the same principle as the flask itself: serviceable, durable, and built to endure. This is proper care — executed with precision.
