This is a B4 business bag from Acegene. There's a document pocket on the back, making it easy to take out magazines, etc. It was used for about a year, but I've been using a backpack, so it's been sitting unused. Thank you. Outer Material: Nylon Size: 30cm (H) x 41cm (W) x 12cm (D), Handle Height: 9cm Number of Pockets: 10 (3 outside / 7 inside) Weight: 1150g PC Storage Available Description <Product Description> ● Equipped with basic functions required for business scenes, such as a PC storage pocket. The front pocket is equipped with a variety of pockets to classify and store pens, business accessories, and other business tools. ● The material is 1260dn Oxford nylon. It uses a strong and flexible material, achieving excellent abrasion resistance and durability. ● The 3D curved pad (3D shoulder pad) reduces the burden on the shoulders. Furthermore, the D-rings attached to the belt joints provide a high level of fit. ● The front handle, which rests on the palm of the hand, is soft, and the rear handle, which touches the fingertips, uses a hard material, creating a hybrid handle. We pursued the ultimate grip comfort.
