Mivv Gp / Mivv storm Gp

[nickodemon]

Does anyone know the difference between the mivv gp can (300mm) and the mivv gp storm (300mm) The price of the storm is considerably less, but i can't see the reason it's cheaper. The links show the storm as plain stainless and the gp can as black, but you can get the storm in black at same price as stainless (Couldn't find one on ebay!)
