Thank you for viewing. This is a simple and functional ACE World Traveler B4 size black business bag (with shoulder strap). I liked the expandability feature, which allows the first compartment to expand by 4cm with a zipper, and I purchased it for one- to two-night business trips, using it twice. The condition is beautiful, but I will sell it to someone who understands that it is a home-stored item. (No pets.) ≪Functionality≫ 【2 Compartments】 Two-compartment type for separating luggage. 【Storage Size】 B4 size can be stored. 【PC Storage Size】 A pocket for storing a 15.6-inch PC is equipped on the front side of the main compartment. 【Main Interior】 There is a zipper pocket x 1 on the back side for storing documents, etc. separately. 【Front Zipper Pocket】 Inside, there is a small zipper pocket x 1 and a pen holder x 1. Small items can be stored and taken out smartly when needed. 【Handle】 The handle uses PVC, making it easy to grip and hold. 【2WAY】 2WAY specification that can be used as a handheld or shoulder bag. The shoulder belt can be adjusted to fit your body. 【Set-up】 Can be set up on the system handle of a suitcase. 【Expand】 Equipped with an expand function that allows for capacity expansion.
