This is a vintage Crayon Shaped Lava Lamp. It has a light blue base and cap. The base is metal and the cap is plastic. It has a glass tube with black Crayon marking blue liquid with yellow lava. The writing shows some wear. It gets real hot when lit up. Look at the pictures. Please email any questions. I will not give feedback until a positive feedback is left for me.
