Add a sharp dose of workplace humor wherever questionable decisions are made. This kiss-cut vinyl decal features a tongue-in-cheek warning sign with a skull-and-crossbones graphic and bold red lettering: “DO NOT DUMB — VERY DANGER TO DUMB HERE.” It brings playful, Salty Dad inspired chaos to laptops, lockers, toolboxes, office doors, water bottles, and other smooth surfaces, speaking directly to the coworker, prankster, or safety-sign enthusiast who appreciates a ridiculous warning with a straight-faced delivery. Choose a satin, glossy, holographic, or transparent finish, along with four size options. The durable vinyl is water-, scratch-, and UV-resistant for vibrant outdoor use, while the removable adhesive lifts away without residue. A 1/8-inch white kiss-cut border gives the design a clean sign-like edge. Please note that multiple decals may share backing paper, the backing includes a small barcode, and very close details may cut as one shape. Lighter designs may show a subtle grain pattern from the printing process.
