Durability: A durable swab is important, as it will be used frequently and needs to withstand wear and tear. Libretto clarinet swab is made from high-quality materials that can withstand repeated use without fraying or falling apart.
Smoothness: Libretto cork grease is smooth and easy to apply. It does not cause any resistance or drag when applied to the cork, making it easier to fit the instrument parts together.
Non-toxic: As we choose the best materials from Japan to make cork grease, it is definitely safe to use and does not pose any harm to the musician, the instrument, or the environment.
Scent-free: Libretto cork grease does not have a strong or unpleasant odor so that it will not distract users during their practicing or performances. A scent-free cork grease is ideal for musicians who are sensitive to smells.
