I'd love to take credit for this but I won't.....
Our mates over at watercoolinguk.co.uk informed us this will be available soon from Feser. It is white like MILK but glows UV Blue under UV light
We will be stocking it as soon as it's available as will watercoolinguk.co.uk
More info will follow when I know a little more but all credit to the hard working at WCUK for this one
