This is a vase with flowers as its main component. Vases have developed as works of art in their own right, and can be considered works of art even without flowers. On the other hand, the original role of a vase was to harmonize with flowers and enhance their beauty. Just as many industrial products and clothes are made to fit people, this vase is made to fit flowers. It can be adjusted to fit the flower in the same way that a zipper can be raised or lowered to fit a garment. Like as if putting clothes on flowers.
