I'm starting work soon and will need a strong sturdy bag to carry a large A4 ring binder type folder and some papers and was wondering whether the above bags are strong enough. I would also like to use the bag for holidays to carry around dc stuff. In the past for work I have used Orla Kiely Tesco jute bags but now I fancy something a bit smarter. Which would you buy? I know they are priced differently and am fine with that.
