Brand new Mathmos Astro baby Lava Lamp + replacement bottle ?

Brand new Mathmos Astro baby Lava Lamp (Yellow-Red bottle) + replacement bottle (Violet-Red bottle) The lamp is worth 50. The replacement bottle is 24. I am selling both together for 50 o.n.o It´s never been used or even taken out of the box, an unwanted gift as i already have one. Collection only, I live in Clapham Junction and work in Farringdon so should be easy to arrange to pick up. The photo shows the box it came in which has a picture of the Rocket lamp but it is labled wrong. It is actually the Astro Baby
