Cultural Tip
In many Spanish‑speaking countries lockers are called "casilleros" (not "lockers"). The informal imperative "Usa" is appropriate when speaking to peers or when the sign is meant for a general audience. For a more formal setting you would say "Use un casillero pequeño" (usted form). Also, adjectives usually follow the noun, so "casillero pequeño" sounds more natural than "pequeño casillero".
