These green wet floral foam bricks are super easy to use. First, soak them in water until they're completely wet. This won't take long because they absorb water really fast. Once soaked, you can cut the foam to fit whatever container you have. It's lightweight, so handling it is a breeze. You can use these bricks with real, dried, or artificial flowers. They'll hold your flowers in place nicely and keep them looking fresh for a long time. Just remember, this product only includes the foam bricks. Any other decorations you see in pictures are not part of the package. There's no special maintenance needed for these foam bricks. Just store them in a dry place when not in use.
