Each year, stallion owners invest thousands of dollars into marketing their studs. A good chunk of that budget is set aside for promotional materials that are given out as freebies, often including handy items such as hats, cups, coozies, towels, and sunglasses–or items practical for the horse owner specifically, such as tail brushes or hoof picks. More unique items like phone-charging stations, temporary tattoos, candles, phone covers, notepads, and nail files have all made their debut as marketing tools in the equine world, as well.
