The Filecorp 3 part tube clip is a very cost effective and space efficient device for securing documents, in order, in your file. This clip functions broadly on the same basis as the lever arch clipping mechanism - but is more flexible, less obtrusive and less bulky. Photocopying specific documents in the file can be acheived without having to remove them from the file. Available in packs of 20 or 100 sets of 3 pieces
