Saikai Japanese Flower Frog

Meaning "mountain sword" in Japanese, these ingenious brass and steel flower frogs (also known as “kenzans”) are used to anchor the stems of flowers, woody branches, and even succulent leaves in place when making arrangements. While these kenzans are specifically designed for the stunning pared-down beauty of ikebana flower arrangements, they are suitable for any arrangement that needs a little architecture. 

To use: position the base in the bottom of your vessel, stick stems into it, and add water to submerge.
