Inner circumference: 16.5cm, beads 12mm ★ "Rakurai no Ki" (Lightning-Struck Wood) refers to wood that has been split by natural lightning, typically including Japanese zelkova nuts, willow wood, and other weather-resistant woods. These trees are struck by lightning on rainy days during their normal growth process, becoming lightning-struck wood. ★ The general belief among the people is that lightning striking a tree is the work of the heavens, splitting it, and that ghosts deeply fear it, making it a powerful talisman to ward off evil. Lightning-struck wood is considered the supreme sacred wood in Taoist magic and was used to create spiritual artifacts. 【Special Notes】 ★ The photos were taken by an amateur using an iPhone and are posted as is.
