Your screen is always covered in finger grease and humidity can be the worst enemy of all. Luckily now you can get great styluses with dust plugs for your 3.5mm head phone jack. It is a great way to plug up that hole and keep the dust out from behind the screen. Best of all your stylus will always be handy and you can keep your screen free of greasy fingerprints. - Material: metal + rubber head - Retractable design - With anti-dust plug for audio jack - Works with any devices with capacitive touch screen
