Please note: 1. Use the clip to lock the closure by sliding back and forth 3 to 4 times. 2. Open the blue cover of the turbo valve and suck out the air with a vacuum cleaner. Please do not remove the pink air cushion. 3. Close the blue lid immediately after pumping. 4. Make sure the zipper is closed. The slider and the blue lid are completely leak-proof and the vacuum bag makes no leakage noise.
