The Fresha Flora Disc is an anti-microbial disc that is placed in a flower vase. It increases the life cycle of the flowers for up to twice as long keeping them healthy and helping them blossom for longer. The environmentally friendly disc also keeps the water smelling fresh eliminating the need to change the water and keeps the flowers, the vase and the general environment cleaner and fresher. As a result, there is no need to change the water whilst the disc is inside the vase. The science behind all of this is due to the anti-microbial action of the 99.9% pure silver disc which kills off all fungal, bacterial and viral micro-organisms. This product is therefore a perfect gift and enhances the flower buying experience. *There is also a money back guarantee on this product.
