Designer Xiral Segard exhibited her concrete Konkurïto vase during Paris Design Week earlier this month. The modular design was inspired by the Japanese bento box (minus the vegetables). Fabricated wholly in concrete, it consists of  four modular stackable elements, plus a cover. You can stack them in whatever order you wish, and place the water reservoir at either the top or bottom, depending on the size of your bouquet. If you haven’t any flowers, don’t hide the vase in a cabinet; it’s meant to be displayed. The Konkurïto works equally as well as a decorative (and functional) box with a lid.
