The main one has a double zipper opening and closing, and the main file size is B4. Inside, there are 2 free pockets, 1 PC storage pocket, and 2 mesh pockets that can hold folding umbrellas and plastic bottles. On the surface of the main unit, there is a B5 size zipper pocket x 1 (inside open pocket x 2, pen holder x 1, key ring x 1). A5 size zipper pocket x 1. A carry handle loop function is also installed. The main unit weighs approximately 880g and has a reinforced bottom. This basic chemical business series is lightweight, has excellent water repellency, and is highly functional for daily use, making it suitable for a wide range of age groups. The main body fabric is 600 denier polyester oxford, and the back side is made of TPU-treated material. TPU (thermoplastic polyurethane) is lighter and more durable than PVC, and is also environmentally friendly, so it is a process that is widely used by outdoor brands. While focusing on lightness and ease of use, we used YKK Vislon's high-strength type of zipper called METALUXETough, which looks like a metal zipper. Glass fiber is kneaded into the resin of the Musi (element), making it 165% stronger than regular Vislon fasteners and 56% lighter than metal fasteners. The lining is made of 420 denier nylon oxford and has been treated with a Teflon fabric protector to increase its durability. Taking advantage of its property of not attracting dirt easily, the gray color is used to improve the visibility of the contents of the bag. It has a pocket suitable for storing a PC or tablet, and also has a trolley bar threading function.
