This is a plug to prevent dust and other particles from entering the USB-C port. It protects the charging port, which is prone to failure, and safeguards your precious smartphone ✨ I use it myself, and it's very useful because I don't have to worry about water droplets or dust. It's small, so be careful not to lose it!! Material: Aluminum Quantity: 3 pieces * Please note that there may be minor scratches due to being made overseas. [Compatible Models] iPhone 15, 16, 17 series, USB-C type iPads, AirPods Pro, Android smartphones, tablets, laptops, Nintendo Switch, and other gaming consoles... Convenient for port protection and looks neat! It doesn't feel out of place even when attached.
