Hardware stores (in a number of countries, "shops"), sometimes known as DIY stores, sell household hardware for home improvement including: fasteners, hand tools, power tools, keys, locks, hinges, chains, plumbing supplies, electrical supplies, cleaning products, housewares, tools, utensils, paint, and lawn and garden products directly to consumers for use at home or for business. Many hardware stores have specialty departments unique to its region or its owner's interests. These departments include hunting and fishing supplies, plants and nursery products, marine and boating supplies, pet food and supplies, farm and ranch supplies including animal feed, swimming pool chemicals, homebrewing supplies and canning supplies. The five largest hardware retailers in the world are The Home Depot, Lowe's (both of the United States), Kingfisher of the United Kingdom, Obi of Germany, and Leroy Merlin of France.
