I purchased this approximately two years ago and used it for about one to two months. I believe it has hardly been used. It's large enough to fit a 16-inch laptop. A waterproof cover is stored at the bottom and can be attached on rainy days. The model number is FR38400313318, as written on the tag. I searched the model number online and have quoted and listed the following: Size (cm): Handle 74, Depth 10, Height 47.5, Width 24.5, Other sizes Main Material: 100% Nylon Thank you.
