A mustard square stud is a bold yet stylish accessory that combines geometric simplicity with a warm, earthy tone. Clean square design with defined edges, offering a modern and structured look. Rich mustard yellow — a muted, golden hue that adds a pop of color without being too bright. Can be crafted from resin, enamel, acrylic, or matte-coated metal, giving it either a smooth glossy or velvety matte finish. Typically small to medium-sized, making it noticeable but not overpowering. Contemporary and chic, perfect for adding a subtle statement to casual or smart-casual outfits.
