**Note: Bubbles, adhesive marks, and loose thread ends are normal handcrafted traces and do not affect wear. The butterfly charm is made of sticker and resin, not an industrial product. All pictures are taken from real products. The chain is made of copper with long-lasting color retention. Avoid contact with water and cosmetics while wearing and store it sealed when not in use to extend its lifespan. This is not high-end jewelry; beauty is its unique feature. Please do not expect perfection.
