So I purchased a Keji Flat File A4 Assorted Colours 6 Pack from Officeworks but when they arrived I wasn’t sure how to use the fasteners.

I searched for how to use keji flat file but didn’t turn up much.

Reading about Keji Flat File Report Covers on eBay I learned that the correct term for the fasteners is “prong fastening system”.

So I searched for how to use prong fastening system and found what I was looking for!
