Yes. Developed in France, the intricate preservation technique allows our roses to maintain their fresh appearance for prolonged periods without water and sunlight. The technique uses a glycerin based solution, which is natural and nontoxic. Often found in skin moisturizers, glycerin allows the flowers to absorb moisture from the air, keeping the petals soft and lively. All of our arrangements are made with these special Everlasting Roses and can last up to a couple of years under good care. Infused with long-lasting Jo Malone natural fragrances, Bovi Box™ is the ultimate luxury flower gift for all occasions.
