Very good product. This oil helps to clean and maintain the buttons on the guitar. The product is cheap and efficasse. One bottle will last you several years certainly. This oil penetrates deep into the wood. The smell is very agrèable. Indispensable for guitarists who like to take care of their equipment. Warning: this product only with the keys in focntionne palisandre (Gibson type). Not to be used on the fretboard in clear varnished wood (Fender type).
