The materials of schoolbags are more diversified. Mickey schoolbags made of leather, PU, polyester, canvas, cotton and linen lead the fashion trend. At the same time, in the era of more and more flaunting individuality, simple, retro, cartoon and other styles also meet the needs of fashion people to publicize individuality from different aspects. The style of Mickey's schoolbags has also expanded from traditional business bags, schoolbags and travel bags to pen bags, zero wallets and small sachets. The price is also rising, and the materials are becoming more and more novel! At present, many schoolbag manufacturers have begun to pay more attention to the carrying system of schoolbags. Considering that there are many books and various learning tools for students to go to school, and many of them are heavy, it is very difficult for students to carry them.
