Kenzan flower frogs or pin frogs are essential accessories for Ikebana arrangements. Each pin frog is reusable and features small spikes that hold flowers in place within the arrangement. Each pin frog is weighted to stabilize your arrangement. The slotted spikes make it easy to interweave your stems while still absorbing water and nutrients. Pin frog measures 3.5''L x 2.25''W x 0.75"H. The Sun and Moon transformation can be used with the two pieces spaced out or attached. Made in Japan. Made of brass needles and a lead bases. Primary Use: Used to hold flower stems in place. Ideally suited for shallow containers but also works well with deeper containers.
