Small Natural Rock Slate Ikebana Vase, Size 4" to 6". Each Slate Vase is carefully hand sculpted in Seattle by a local artist. Featuring unique, low profile styling, they hold a single flower, a budding branch or a few delicate blossoms. You can create a dramatic arrangement almost effortlessly. Each Vase reservoir cup holds several days worth of water and contains a permanently attached Kenzan (Pin Frog). They may also be used for silk or dried flowers. We also love to grow "Lucky Bamboo" in them for a "Feng Shui" look.
