Using these table lamps is a breeze. Just plug them into a power outlet, and you're ready to enjoy the soft, warm light. To attach the linen shade, use the harp shade fitter on the lamp base. You can charge your compatible electronic devices like phones or tablets using the built - in USB port. When it comes to maintenance, use a soft, dry cloth to wipe the white polyresin base and the linen shade. Avoid using harsh chemicals or abrasive materials as they might damage the lamp. Since these lamps are not for commercial use, keep them in a home environment. Also, make sure to place them on a stable surface to prevent them from tipping over. There's no need for assembly, so you can start using them right away.
