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 setms while still absorbing water and nutrients. Pinfrog measures 1 1/8" in diameter and 7/8" in height. Primary Use: Used to hold flower stems in place. Ideally suited for shallow containers but also work well with deeper containers.
