Using this table lamp is easy. First, assemble it following the provided instructions. Once assembled, screw in an E26 bulb that's greater than 100W (the bulb isn't included). Then, place the lamp wherever you need some extra light in your home. As for maintenance, refer to the Concrete Care Instructions Manual. Remember, small cracks, chips, and navots are normal for concrete and add to the lamp's character. Don't worry about minor non - structural blemishes. If you ever need to repair the concrete, check out the instructional video we've provided.
