Featuring the perfect curved design, Classic Kidney is an heirloom-quality kidney flask that is hand molded to fit your front or back pocket. Its body is made of 22 gauge solid copper—finished off with our ultra-reflective SuperPolish™ finish—while molten, lead-free tin is applied to the interior using a lost process that's proprietary to our company. Makers of copper flasks for more than 200 years, Classic Kidney is hand built with devotion, skill, and the utmost attention to detail. Extremely versatile for everyday use.
Note: Minor imperfections may occur and are a natural part of the 100% handmade process, lending character and charm to each piece.
