Apply even pressure using a heavy object for 20–30 minutes. Alternatively, fully open the top cover (up to 180 degrees) and release it repeatedly until the rebound force reaches your desired level of tension. ⭕️PURCHASE NOTES * For MacBook Users: Please ensure you select the correct Smart Sleeve model based on your MacBook’s year, model, and size to guaranteed a precise fit. * For Non-MacBook Users: Due to varying laptop dimensions, please verify that your device fits within our recommended size range to ensure stability and prevent shifting.
