[From commuting to school to mother's backpack] It is a large-capacity women's backpack that can be used not only for daily commuting but also for business trips of about 1 night and 2 days. We thoroughly pursued not only the size but also the choice of materials and ease of use, and packed a lot of functions. Based on customer feedback, we have realized a size that can fit not only A4 documents but also 13-inch computers. I also devised the thickness of the shoulder belt so that my shoulders do not hurt even if I put a lot of luggage. Please experience the carefully selected BLUE SINCERE rucksack. [Convenient 3-way specification] It is a convenient model that can be used for backpacks that can be used to open both hands, a hand tote that can be held quickly, and even shoulders. It is a simple design that can be used properly depending on the daily scene and can be shared among family members. [9 pockets & large capacity] A large number of small item pockets are arranged from the voice of wanting to sort small items in detail. There is a dedicated pocket for smartphones in the front space, so you can quickly store your smartphone. There is a security pocket on the back, and it is designed for peace of mind to prevent theft when traveling abroad! In the side space, you can store PET bottles and umbrellas, so you can make full use of the space. [Can be used for a long time in new condition] The material is PU leather (shrink) so that it can be used hard every day, so scratches are less noticeable. Keep it in pristine new condition. It does not require maintenance, so even busy women can use it without stress. (If it gets dirty, wipe it off quickly with a cloth dampened with water.)
