Preserved flowers are natural flowers that are hand-picked and cut at the peak of blooming beauty, then delivered to the factory for further sorting, grading and finally processing. This secret patented preservation process allows the flowers to maintain their beauty, soft and delicate appearance for a long time. They typically last more than a year but again it depends on environmental conditions. i.e: The same batch of flowers may last differently basis on their display area that could be exposed to different conditions which are unaware to the untrained eyes, like humidity. They succumb to heat, sunlight, water, wind and esp humidity.
