Thank you for viewing! This is a shaker keychain made with resin. There is no oil inside, so it makes a shaking sound. There may be imperfections such as dust, uneven coating, scratches, distortions, air bubbles, burrs, and dirt. The color may appear different from the actual product depending on the lighting and the device you are using. Please purchase only if you understand that this is a handmade item made by an amateur. If you have any questions, I will answer them in the comments section.
