Preserved roses are 100% real flowers. They aren’t made from silk or any other material even though they may look fake from afar. To properly preserve these flowers, it’s critical that your roses were cut when they are at their most beautiful. The flowers are then put into a mixture of glycerin and other plant elements. This rehydrates the rose from its petals to its stem and replaces the sap within it. After a few days, the process is complete and you have preserved roses that are flexible and look natural.
