316 Surgical-Grade Steel. Built Like a Tank.
Most tumblers use 304 stainless. This one uses 316 — the same grade used in medical equipment and marine applications. It resists corrosion, won’t leach metals, and lasts decades. The matte black finish and clean lines make it the only tumbler a man doesn’t feel embarrassed to pull out at a meeting.
