PC Packing Foam According to our experience, when using the expanding foam bag to protect your computer, you should place it in the computer case as soon as the bag starts to expand. The bag will automatically adapt to the shape of the computer inside, providing protection. Do not wait until the bag has expanded significantly before inserting it into the computer case, as the metal of the case may cut into the already expanded bag when forcefully stuffing it in . Also, you should not forcefully stuffing 2 bags at the same time as the pc case is not enough . If it is really necessary to use 2 bags, please wait until the first bag is completed before putting in the second one.

Wait for liquid expand and break through L/R area, quickly distribute liquid evenly throughout bag. Note: Only simple spreading the liquid to all corners of the bag is required here (e.g., follow the video instructions).
