Made of durable and lightweight nylon. Size: Width: Approximately 40 cm Height: 60 cm Depth: 20 cm Two zippered pockets on the front. The casters move smoothly. I purchased this in the US a few years ago and only used it once for a one-way trip from the US to Japan. There are some minor scratches, but I think they are not noticeable during use. Recommended trip length: 4 days to 1 week Please note that it will be shipped in simple packaging, just a plastic bag. Thank you. ☺️
