How to use sponge in protective box

The protective cotton of the protective box is generally divided into three kinds of sponges: wave cotton, plane cotton and pre cut cotton. Wave cotton is placed on the top of the box. Flat cotton is a thin layer of sponge. It is placed on the bottom of the box, and then pre cut sponge is placed to fill the box. Pre cut cotton accounts for the largest proportion of box sponge, also known as pre cut block sponge, checker sponge, universal hole sponge and so on. This kind of cotton is designed to facilitate people to quickly dig out the corresponding inner space shape in the box sponge according to the shape of their own equipment when they install their own equipment, which is not as fast as possible, and the inner space dug out is relatively good-looking. If you don't say much, the picture above will be clear at a glance.
