The lock at the top corner holds it all together

Love the corner lock to keep documents (including smaller items like receipts and Post-It notes placed in the front of the folder) secure - the front clear corner slips easily into the corner locking pocket.

The are by far the best corner lock document to put ones paperwork when going to an interview

The corner lock holds papers well and easily opens when you want to
