Based on the popular Kunai pendant by Vitaly, the Tensho is named after the era in Japanese history when the kunai was invented as a farming tool, and later adopted by ninjas as deadly weapon. This single earring features a solid, squared-off hoop with hinging pin mechanism. Great to wear alone or mixed alongside other earrings and ear cuffs. A true statement piece, for men and women! Materials: Stainless Steel NWT original box and packaging included, never worn. Love this piece but the style does not suit me.
