Multi-functional backpack purchased from the Brederick official website. Lightweight and waterproof, can accommodate a 13-15 inch laptop. It has enough storage for a lunch box, water bottle, shirts, etc., making it perfect for commuting. There are no noticeable scratches or stains, and it's in beautiful condition. Size: Approximately 42cm (H) x 24cm (W) x 14cm (D) Capacity: Approximately 14L Color: Black Material: High-density polyester Thank you for viewing. Used a few times. I think the condition is very good. How about it for business trips or those who work night shifts? Please refrain from purchasing if you are looking for perfection or are overly concerned about cleanliness, as this is a used item.
