This glossy black ceramic mug brings a rugged, work-ready vibe to morning coffee. The heavy-duty badge-style graphic reads like a small anthem: Blue Collar — Cold Air. Hot Coffee. It’s the kind of cup that warms rough hands and starts slow conversations before the sun comes up. The deep black glaze makes the printed colors pop — rust, cream, and denim tones sit bright against the dark background. Use it on the jobsite, in a garage, or at the kitchen counter to hold long black coffee, strong espresso, or whichever brew helps you wake and move. The comfortable C-handle and sturdy ceramic body feel familiar and dependable every time you reach for it.
