This bag is in perfect condition except for two minor pen marks, which are shown in the picture. It is absolutly 100% authentic. I am open to reasonable offers. Here is a breakdown of the dimensions: Width: Approximately 14.6" to 15.0" (37cm to 38cm). Height: Around 10.6" to 10.7" (27cm to 27cm). Depth: Roughly 3.9" to 6.7" (10cm to 17cm), with one source listing a smaller depth of 10cm. Shoulder Drop: Approximately 16.5" to 18.5" (42cm to 47cm), with a range of adjustability. It's worth noting that minor discrepancies can occur between different listings, often due to slight variations in measurement methods or different production years.
