I bought about 5 packs of suspension folders from Tesco a while back only to find that my filing cabinet is just for folers and not suspension folders haha. So I have got at least 5 packs of these maybe more. They are an orangey colour but the same as the ones in the link here.
Anyway, minimum of 5 packs, will check actually how many in the morning. Asking for £15 ono. Cheers.
