These kenzans are ideal for ikebana displays and western style flower arranging. The brass pins are strong enough for woody material, as well as soft green stems. Select the size that works best for your arrangement and place at the bottom of a vase or container. Then simply cut the flower stem to the desired length and impale the stem on the prong. This will help water enter the stem and extend the life of your flowers. We also love the double duty use of these mini frogs as candle stands with our Wax Atelier candles . Available as a Mini Frog Set of 4, or individually as Medium or Large frogs.
