Ex-Royal Mail bike pannier bag set
De-badged Royal Mail panniers as used when Postman Pat wasn't the only postie with a van.
These tough bags are made of thick nylon with a harness that has clip-buckles to hold each bag together across the bike or cycle rack. Of course you'll need a suitable rack to support the bags and keep them in place, but for not very much, you have a great starter pannier set.
The bags can also be put to other uses of course, such as car tidy-bags, horse saddle-bags, household/garage storage - you name it.
In good condition but may have signs of wear or hand-written marks on.
