Bamboo Stylus rubber nibs are made from high-quality materials to provide the best screen feel and experience. However, like with most other things, excessive or prolonged use may lead to signs of wear on the nibs. We rigorously test all Bamboo Stylus products to ensure they can be used for as long as possible. Depending on the level of use, it may be necessary to replace them. The rubber nib design eliminates the need to apply strong pressure on the screen while using it, which helps extend their lifespan. It is advisable not to drop the Bamboo Stylus, as this can cause premature nib damage.
