The oils and oils on your hands may leave marks. If you are concerned, please wear cloth gloves. In addition, if you store it in a place with as little humidity as possible, and clean it by applying beeswax or cooking oil to the entire surface and wiping it with a soft cloth, it will be less likely to get fingerprints and will be cleaner. If patina appears and there is no change in the sound, you can use it as is. If you are concerned about it, try polishing it with a mixture of vinegar and salt, metal polish, or sandpaper. If you drop it and it becomes dented or the sound changes, please contact us so that we can reshape it and re-articulate it without trying to fix it yourself. click here to learn how to make Orin ring.
