This is a keychain made with resin, approximately 5cm in size. It does not contain oil, so you can enjoy the color combination of the blue background and pink beads. *No oil is used inside. The beads will move around with a shaking sound. While made with care, due to being handmade, there may be air bubbles or dust. Also, the hardware is not as strong as commercially made products, so please handle with care. #Snow #Crystal #Blue #Pink
