This is a MILLET INSPIRANT backpack. Model number: MIS0604 Originally, it had a vinyl coating on the surface, but it deteriorated over time and became flaky, so I removed it as much as possible. Because of its design, which is similar to the current EXP, it has many pockets and I think it can be used for business. Please check the dimensions in the images. No claims and no returns. Size: 11-25 L
