Made to order. Please allow approximately 2โ€“7 business days for production, plus shipping time. Production and delivery may take longer during holidays and other high-volume periods.

This glossy black ceramic mug carries a bold, vintage mechanic vibe. The distressed cream lettering and crossed wrenches read “I Speak Fluent Engine,” giving it a worn-in, workshop-ready look.

Machine wash cold. Tumble dry low. Iron on steam if it needs it, medium heat.

Skip the dryclean. Skip the bleach unless you have to.

This shirt’s pre-shrunk during the garment-dyeing process โ€” so what you order is what you’ll still be wearing after washing twenty times.

Shipping
Every piece is made to order. Production takes 3โ€“7 business days, then it ships โ€” 5โ€“10 business days after that, US only for now.

No warehouse full of guessed sizes sitting around. That’s the tradeoff for a shirt made specifically for you.

Returns
Since it’s custom-printed, we don’t do buyer’s-remorse returns. If it shows up wrong โ€” damaged, misprinted, not what you ordered โ€” send us a photo within 7 days and we’ll fix it. No hoops.

Sizing
Check the size chart before you order. When it’s close, size up.

FULL DESCRIPTION

Description

This glossy black ceramic mug carries a bold, vintage mechanic vibe. The distressed cream lettering and crossed wrenches read “I Speak Fluent Engine,” giving it a worn-in, workshop-ready look. It feels like that first warm cup handed over between jobs — gritty, familiar, and made for someone who lives with grease on their hands and pride in their craft. Use it while tuning a carburetor, sketching out schematics, or simply sipping coffee before an early shift. The deep black finish lets the design pop and the sturdy C-handle sits comfortably through long mornings and cold nights. This mug slots naturally into a toolbox-themed kitchen, a garage bench, or a late-night work desk, and it resonates with anyone who talks in torque and thinks in horsepower.
