When you are moving out, you think about having moving boxes in order to have your things properly placed.  However, you forgot to realize that there are different types of moving out boxes - the regular ones (the ones you see in your house or the boxes you buy from a store) and the certified boxes.  For most people, they do not really realize the difference between the two. In order to help you understand the difference between the two, the following are given:
 
Certified boxes were made, designed, and manufactured in order to eliminate compression of things when they are stacked or placed inside a moving van or dolly.  The certified boxes are capable of being stacked on top of the other without putting much pressure on the one that is at the bottom.  A certified box is capable of withstanding the pressure of stacking various boxes without "hurting" the others.  Certified boxes come in different sizes and forms in order to address all the moving out needs of people.  Certified boxes are answers to all the moving out needs of movers.  They come in different sizes because they know that movers have different needs.
 
With these, it is assumed that one would learn and understand the compelling difference between a regular box and a certified one.
