Can you find a smaller box or cut the height down to make it smaller?
Remember, we do NOT need any chargers or cords, and not much padding is required as the most fragile part of the laptop is already damaged.
Also, check you are using Centimeters (cm’s) not Millimeters (mm’s)
Here is a YouTube Video that may help if you are planning on cutting the box down.
A common size for large laptops we get in is approx.
Length: 45cm x Width 35cm x Height 12cm
If you need to source a new box check local shops, (they like to get rid of them) or purchase one from post offices, office supply shops, and hardware stores.
