chipboard planks (Bolton le Sands LA5)

Further items from my recent loft clearance: 2 large chipboard planks, 45cm x 85cm approx. Left over fitted furniture I assume as there are various screw holes on one side of each plank but this sort of wood can always be turned into decent shelving or similar. One plank has a small scratch on the good side but the other plank is in perfect condition on one side.
