A: I haven't bin anywhere!
I don't normally cover panniers but they're still the most common way of loading a bike and these are tough. BikeBins are made in the UK from 2.5mm thick, hard polypropylene which should protect your books, laptop, tools or WHY. The panniers have lockable lids and can be secured to the bike with a chain or steel wire lock.
BikeBins are available from the manufacturer's website in various colours , you can even specify differing lid and body colours or have your firm's details emblazoned on the sides.
When your off the bike you can carry the BikeBins by their handles or on shoulder straps (included). A pair of these panniers in black delivered in the UK will cost you a mere £62. Each BikeBin Carries 17 litres of stuff. All the dimensions are on the web site.
