This mechanic is the NEW Midnight foam from Oasis Floral Products. Out of the box, this foam is a charcoal grey and when soaked with Flower Nutrient Water, it turns “BLACK”! This is a great new innovation because black foam virtually disappears in the arrangement…and the areas where it is visible appear to be shadows (rather than sticking out as exposed foam). It also allows for the foam to be visible in more modern arrangements. It’s a great innovation and Midnight Foam looks amazing in any arrangement!
