Made to order. Please allow approximately 2–7 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 brings attitude to every morning routine. Featuring a bold, mechanic-themed illustration — skull with a wrench, gears, and rugged typography reading “Fluent in Grease, Gears & Grumbling” — it’s built for hands that like their coffee strong and their tools louder. The deep black finish makes the vibrant printing pop,…

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 — so what you order is what you’ll still be wearing after washing twenty times.

Shipping
Every piece is made to order. Production takes 3–7 business days, then it ships — 5–10 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 — damaged, misprinted, not what you ordered — 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.
