These are very light paper quilling pierced earrings, weighing only 0.05oz(1.3g). How to Care for Paper Jewelry: I use synthetic resin paint to provide extra sturdiness to the jewelry. These earrings will withstand daily wear, including light sweat, moisture, and water splashes, but they are not 100% waterproof. Please avoid swimming or showering with them. If the product comes into contact with water, wipe it with a paper napkin, allow it to air dry naturally, and it will return to its original condition.
