Artist's mountboard offcuts, also studio background paper (Presteigne LD8)

A large quantity of good mountboard offcuts, various sizes, mostly Smooth Antique White but other finishes too. Includes a good number of ready cut mats in different sizes. I need it all gone asap, otherwise it will have to go to the tip, which seems a waste. I also have various end rolls of studio background paper which need to go too, width about 2.4m, lengths variable
