Customizing backpack requires a back cushion to support the weight, balance the overall stress and weight, and combine the child's body structure to minimize the presence of high and low shoulder backpacks behind the child's back.
2. Customizing schoolbag requires adjustable chest buckles that secure the weight of the schoolbag in both the front and back, making it actually easier to carry without causing damage to any part. Moreover, children like to run and jump, and after fixation, the stability is also good. The weight bearing of the schoolbag is also relatively uniform, which can increase the service life of the schoolbag.
3. The customized size of the schoolbag should conform to the child's height and physique, with a width not wider than the child's body, and a length not greater than 10 centimeters from the child's waist. Being too large or small is not only detrimental to the child's bone development, but also not beautiful to carry.
4. The shoulder strap and back are made of high-density mesh material. If the mesh is too large, it can easily be caught by sharp objects. If the mesh is too small, it is not conducive to heat dissipation. In summer, carrying a back is like carrying a boiling kettle.
5. Then it's time to customize the interior space design of the schoolbag, with basic compartments and classified bags. The simpler the zipper hardware inside, the better.
