Kenzans have held up flower arrangements for hundreds of years, long before anyone thought to call it ikebana specifically — a heavy base studded with metal pins that a stem presses onto and simply stays where it's put, no wiring or floral foam required. Cutting stems shorter to fit the pins isn't a compromise; shorter stems have less distance to pull water through, so arrangements built on a kenzan tend to last noticeably longer than ones crowded into a narrow vase neck. Nine sizes are available here, from a compact 1.4-inch round suited to a single stem up to a 4.2-inch Sun and Moon shape built for something more ambitious. Round and rectangle options cover most bowl and dish combinations in between. The pins themselves are simple, but the principle behind them has outlasted nearly every flower-arranging trend that came after it, which says something about how well a good, unglamorous idea holds up over time.
