This is a Millet backpack. It's convenient because it can be made into two compartments with a zipper. I received it from an acquaintance and used it on and off for about a year, so it shows signs of use, but there are no damaged parts, and I think it can still be used. I apologize if I missed anything. For reference, I took photos with a clear file, so please use them to get an idea of the size. Even just the upper part of the two compartments can hold A4 size items. Also, there is no tag, and the details such as the capacity are unknown, but I think it's about 22 liters. Measurements by a layman: 48cm x 29cm x 15cm - Color: Black - Brand: Millet - Type: Backpack - Features: With front pocket - Capacity: Large capacity Home cleaned I will fold it and ship it.
