Please confirm your iPad model before purchase, selecting an incorrect case would not be compatible with your iPad.
You can find the model number in two ways:
Look on the back of your iPad.
Open Settings, tap General, then tap About. Look for the model number in the top section. If the number you see has a slash "/", that's the part number (for example, MY3K2LL/A). Tap the part number to reveal the model number, which has a letter followed by four numbers and no slash (for example, A2342).
