This black t-shirt features a clever design for dads with a sense of humor. The shirt reads "I TELL DAD JOKES PERIODICALLY BUT ONLY WHEN I'M IN MY ELEMENT", with "Jo", "K", and "Es" displayed in a style that mimics the periodic table of elements. The design is distressed, giving it a vintage look. It's made from a soft, comfortable fabric, perfect for casual wear.
