The pen-shape cleaning kit is the Third Generation of the original version. It greatly improves the convenience of using--just a simple slide without any effort you could start cleaning your devices. No need to pick up the small items one by one nor loosen the lids. You could use its mental pen tip to clean the hard-to-reach corner cleaning earwax or dirt. Then brush them out of the surface of the devices. Use the sponge to clean the inside and surface of the earphone case. You 'll get a new airpod and excellent listening experience.
