Pearls are delicate gemstones that are sensitive to high temperatures and humidity. Paulownia boxes are resistant to corrosion and have insect-repellent properties. They are also flame-retardant and have a constant humidity function, making them suitable for storing items. We highly recommend storing your precious and delicate pearls in these paulownia boxes. The interior is designed to hold a set of earrings or individual earrings, making it very convenient. Includes pearl care instructions and a polishing cloth. This is the price for the box only. Necklace is not included.
