Hello☆ Thank you for visiting my shop from among many others. Panari Blue ☆ 10mm Glow-in-the-dark, phosphorescent type Flower Charm ☆ When you shine the firefly glass in the sunlight, it sparkles and shines very beautifully☆ Ueji Island, Shimoji Island, belonging to the Yaeyama Islands in Okinawa Prefecture. In the Yaeyama dialect, it means "remote island". Called by the locals as "Panari Island", this firefly glass recreates the super beautiful emerald green sea with white sandy beaches that stretch endlessly. It's Panari Blue☆ Each one is carefully made, but due to being handmade, there may be some slight imperfections. We ask for your understanding when purchasing. Hooks and other parts use Surgical stainless steel, which is unlikely to cause allergies. It stays in beautiful condition without discoloration in the dark☆ Earrings can be changed for an additional 100 yen. They are also surgical stainless steel☆
