Looking to buy Mathmos Fluidium

[Mikey]

Hi everyone, been viewing this website for a while and enjoyed the info, and just decided to sign up! I was wondering if anyone was selling or thinking of selling there Mathmos Fluidium. I already have a yellow & green one and im looking to buy more! Unfortunately they seem hard to find on eBay at the moment, but i do know the yellow/green ones are still available on some websites. Thought id ask! Thanks a lot Mike
