Hi Emmeline Decatoria,
To ensure safety of your products, you need to have it place inside a box specially since you mention that it is a monitor and on it's original box indicates the brand of the product. This may cause unwanted attention since it will be of valuable item. And monitor's are sensitive ,they need to be secured and protected from damages. You can do that by wrapping the product with bubble wrap and placing it inside another box with enough fillers to secure it from moving around the box. Item's with package weight or dimensional weight of more than 20kgs must be put in crates, except for non-fragile like mattress, tires and furniture. Putting Fragile sticker or label on it , will let the Courier know to handle the parcel with care.
