This is a roof waterproofing repair kit which includes a roll of sticky tape and a tin of primer.
It was found in an old shed so may be quite old. The tin of primer is still liquid and (at first glance) everything seems usable.
Please say (in your first message) when you would be free to collect, and please give more than one option for collection day. People that do this will be given priority over those that don't bother to.
