Using these table lamps is easy. Just plug them into a power outlet and use the 3 - way switch to adjust the lighting according to your needs. Place them on a stable surface like a side table or a nightstand. As for maintenance, you can use a soft, dry cloth to gently wipe the blue ceramic base and the white linen shade to keep them clean. Avoid using harsh chemicals or abrasive materials as they might damage the lamp. Since no assembly is required, you don't have to worry about putting it together, but still handle the lamp with care to prevent any accidental breakage.
