A4 clear plastic punched pockets x50 (Maidenhead SL6)

These are the clear sleeves with punched holes for filing in various types of ring binder / lever arch folder etc. - or can just be used independently as protectors. I have around 1000 secondhand ones, all recovered during shredding of the contents. There are a few that load from the top as in the picture, but most of these ones load from the side. They are in batches of 50, please say how many you would like.
