Ikebana Kenzan | Pin Frog - Sun and MoonThis Japanese Sun and Moon shaped, brass Kenzan is often used for more complex ikebana floral arrangements. The kenzan also known as a pin frog, is an essential component of Ikebana. Sharp, heavy brass spikes set in a solid weighted base, are used to hold your arrangement upright in your Ikebana vase or suiban ikebana container. The tightly formed pins expand the stems of your flowers and plants, allowing additional hydration for longer lasting arrangements. This Kenzan includes a non-slip rubber ring to use if additional stability is required. Imported from Japan, these are the best quality kenzan produced. Made to last a lifetime, this kenzan measures 4 1/2" x 2 3/4".
