Cleaning your stylus has never been easier! A quick placement of the stylus on the self-adhesive cleaning gel pad NRG30 is all it takes to gently remove dust and other dirt. The reflective surface on the top of the NRG30 packaging also makes it easy to check the system for contaminants. The silicone-based gel pad can be washed with cold water after use to remove the collected dirt. Simply let it air dry without wiping it. The diameter of the gel pad is approximately 35 mm.
