Large coolbox (Stroud GL5)

This is a large Camping Gaz Isotherm coolbox, 42cm high, 42cm wide, 28cm deep. The handle has broken and so you need to use tension straps (which we don't want to give away with it, sorry) to keep it closed and to carry this. We have done this for years and it has been a brilliant coolbox but it is now bigger than we need
