- Clean Your Phone: Ensure your iPhone 11 screen and back are clean and free of any dust, fingerprints, or debris.

- Open the Case: Use the provided open key or a coin to gently pry open the case from the bottom right corner. Carefully separate the front and back covers.
- Insert Phone: Place your iPhone 11 into the front cover, ensuring it sits snugly and all buttons align correctly with the case's button covers.
- Close the Case: Align the back cover with the front cover. Press firmly around all edges of the case to ensure a complete and secure seal. Verify that all clips are securely fastened.
