Lockers are secure storage compartments typically found in schools, gyms, and workplaces. They are designed to hold personal belongings, such as books, clothing, or equipment, and often come with a lock or combination mechanism to ensure safety. Lockers can vary in size and material, ranging from metal to plastic, and are usually arranged in rows for easy access. Users can rent or assign lockers for a specific period, allowing them to store items without carrying them around. Many schools provide lockers to students to keep their belongings organized, while gyms offer them for members to store workout gear during their visits.
