Zerodust Stylus-Tip Cleaner

Zerodust Stylus-Tip Cleaner made of newly developed ultra soft plastic is unprecedented high performance cleaner and easy to use. As the cleaning element of Zerodust is softer and has 15 times more elasticity than a baby skin, this mysterious material will never damage a delicate stylus.

How to Use:
Lightly press a stylus tip once or twice onto the Zerodust cleaning element, and pull it up. The element accepts the tip very naturally and finely removes dusts over the tip for noise and muddy free sound. Dusts now stick to the cleaning element leaving no scum thanks to so designed ingredients of the element material.
Zerodust container case top works as a magnifier convenient for precise check of the tip condition before and after cleaning.
When the cleaning element is stained, wash it in warm water with a little amount of neutral detergent. Dusts can easily be removed, and you can use Zerodust repeatedly and long time.
