Introducing Reva™ - the Expanding Flower Vase! This innovative vase folds completely flat for storage but when it is filled with water it expands into a beautiful, stable flower vase! It is made from polymer plastic and the material is kid and pet safe. Reva™ is ultra-portable and convenient and can be used over and over again. Just rinse and dry it out before storing it for the next use. Since it folds flat you can store a whole bunch in a single drawer!
