OASIS® Floral Foam is both functional and versatile. It's a great way to keep your flowers hydrated and arranged beautifully in containers that are hard to arrange flowers in. The Grande Brick is equal to two standard-sized bricks. Cut the foam into the size needed and place the stems into the foam after soaking in water; the foam is very easy to use and will keep the flowers fresh and the display in place before and throughout the event. Ideal for large events with many centerpieces and arrangements as it saves time and effort when creating the displays.
