This is a large 16.3 inch lava lamp. The lava lamp works perfectly. Please ask any questions. this is the original lava lamp lava brand. You can tell by the bottle cap in pictures also there is a small dent in the 3rd to the last picture can easily be pounded out but I let the new owners do it their way……look on ebay for this lamp and you will not find one the same size and colors especially an original. Lot’s of misconception about these lamps but the originals are the one’s to wait for.
