100% Natural Floral Foam™ is an all-natural product from Agra-Wool International.
The biggest advantage of 100% Natural Floral Foam™ is that it can be used both wet and dry. The 100% Natural Floral Foam™ has an enormous absorption capacity, so it absorbs and retains a lot of water very quickly. Because of its resilience, the foam clamps well in any pot or vase and is easy to cut into any shape. The 100% Natural Floral Foam™ ensures that the stem is firmly attached and is also easy to reposition.
