Be easy, this my 1st posting.
Here we have a Lava Lamp produced by the original and iconic 60's Lava Lamp manufacturer, Mathmos. You'll be hard pressed to find this for less than £50 elsewhere.
If you don't like the lava colour, then it's possibly cheaper to buy this and an interchangeable seperate colour than to buy a different coloured Lava Lamp by itself... If that makes sense?
I'm afraid that there are only 7 left in stock, so be quick if you want one.
