About this product: This smartwatch case is only compatible with Xiaomi Mi Band 9/9 NFC (not compatible with Xiaomi Mi Band 8/8 NFC). It comes in three colors: black, white, and clear. This one-piece, fully covered PC tempered glass case is specifically designed for the Xiaomi Mi Band 9. The glass surface features a high-definition, clear screen protector with a hydrophobic coating, oil-resistant, and anti-fingerprint coating, providing a crystal-clear viewing experience. It can be easily installed and removed from the Xiaomi Mi Band 9. You don't need to remove the case before charging. However, when washing your hands or sweating after exercise, water vapor may form under the screen protector. Remove the case to wipe away any moisture trapped between the screen protector and the watch to prevent it from affecting the screen.
