【Double Head Structure, Removable Design】The multifunctional earphone cleaning pen combines three functions in one portable gadget, each of which plays its own role. Change the head to use a flock sponge, high-density brush or metal tip for different cleaning tasks. Metal tip for demanding cleaning tasks: like the pen tip, the cleaning pen protects the surface to be cleaned with a round head that penetrates deep into the hard-to-reach blind spots and effortlessly scrapes off unruly dirt. Ensure an all-round cleaning and do not leave any dirt. Furry sponge for thorough cleaning: made of fluffy flock fabric, the soft sponge reaches deep into the wireless charging cases and wipes off all dust and dirt. Note: spray some rubbing alcohol on the surface to increase the cleaning power and make the charging case look like new. 【Soft Brush for Effortless Cleaning】A high-density brush gently cleans the dirt accumulated in the sound outlet openings without damaging your earphones. Regular cleaning keeps your earbuds clean and pure, eliminating the negative impact on their performance. 【Easy to Use, Effortless Transport】You just need to turn the inner part and pull out to change the head you need. You can carry and store the cleaning kit together with the wireless charging case when you need it. Tips: It is recommended to wash the sponge with a cleaning solution after use.
