Stanley - The Tough-To-Tip Admiral's Mug 20oz - Matte Black

This retro-inspired mug is made to stay put, no matter where you set it down—truck dashboard, boat console, or even that wobbly desk in your office. The wide base and non-skid bottom are designed for stability, while the double-wall vacuum insulation keeps drinks hot or cold longer. There's even a leak-resistant flip lid that locks in place for security.
