Thank you for viewing. This is the Black Ember Forge 30L. The color is black, expandable from 20L to 30L, and it's a business bag that can be used as a shoulder bag or a backpack. I purchased it directly from the US in 2020. I used it about 15 times for travel and business trips. There are some scratches on the surface and slight fraying on the straps (see images). Because it's from the initial production run, the surface material is different from the current model. The design is sophisticated and satisfies the desire to own it, and you can customize it to your liking with expansion parts. I am selling it because my job has changed and I no longer have a use for it. It is a used item, so please purchase only if you understand this.
