The exterior PU leather looks well made and sturdy while its interior material is so soft and nice. My laptop (13.3″ size) fits well inside the dedicated place and it feels secure even if the zipper is open. So, in case the zipper fails, my laptop won’t fall. The zipper does not stuck and is well made. Its design seems a bit girlish, though.
