Color: Black Size: 3" X 4" X 9" Twin Pack The dark foam recedes visually. This makes it less noticeable inside a glass vase and allows the flowers to catch the eye instead. No need to wrap black foam in foliage to cover it. The black base becomes an element of the on-trend design. Dry gray foam transforms to rich black when soaked, creating the perfect canvas for any design. Foam will turn gray when it needs water again, making it clear when arrangement reguires more water. From traditional to bold, OASIS Midnight Floral Foam fits any style.
