This black t-shirt features a clever geology pun: "I may be GNEISS, but don't take me for GRANITE." The design includes distressed lettering for a vintage feel and an illustration of rocks with a pickaxe. Made from a soft, comfortable fabric, this tee is perfect for geologists, rock hounds, or anyone with a good sense of humor. Wear it to your next geology field trip, rock and mineral show, or just around town to show off your love of rocks and geology humor. A unique and fun addition to any casual wardrobe.
