Upon examining the visuals, no significant deformation such as cracks, chips, dents, or discoloration is observed on the product’s casing or accessories. The fabric, stitching, zippers, and straps of the carrying bag appear sturdy. There are some dust particles on the device’s screen surface, but this does not constitute a permanent defect.
