I am also selling this item on other platforms, so please be sure to check for availability by commenting before purchasing. This is an A4 briefcase from L.E.D.BITES. It features practicality with its expandable width depending on the amount of luggage, and the appeal of the original leather that allows you to enjoy a unique luster and texture through aging. It's a simple black leather bag, but its distinctive feature is that it can be made very thin and stylish when carrying few items. At the time of its release, it was featured in a fashion magazine that highlighted thin briefcases, and it was the clear No. 1 with a 3cm width when new. Another advantage is that you can expand the width significantly by placing a bottom plate inside the bag when it's thin. A thin leather pull tab was originally attached to the opening zipper, but it broke off during use. Therefore, you will need to provide something like a keychain or a replacement pull tab. This zipper has a simple lock key, and I will include the key. You can lock the zipper to prevent it from being easily opened, which can help ensure privacy if you need to leave your seat for a short while. I purchased this bag 12-13 years ago and used it about 10 times a year for business trips and presentations. There are minor scratches and paint peeling due to use on the corners and bottom, but there are no major damages such as tears or rips. The size is approximate, as I measured it myself: Width: 42cm Height: 31cm Depth (when thin): 11cm Depth (when expanded): 3-4cm I hope someone who appreciates a vintage feel will continue to use it.
