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 protects your important 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 game consoles... Convenient for protecting the port and looks neat! It doesn't feel out of place even when left on. Thank you for viewing. #NishiharuList ✳️ Delivered by regular mail. ✳️ Basically, ships the next day. ✳️ Feel free to comment if you have any questions ♪ Instant purchase is also welcome!
