To avoid that the flogbook falls out of the case just slip the elastic over the slip case.
More space required?
If the ball pen bothers you or the logbook enlarges by-and-by you can put the pen holder inside the clips. This makes room for more dive logs and the ball pen is perfectly kept.
That's how it works:
1. Page all of the inlays forwards and open the clips.
2. File the pen holder on the left so that the pen is inside of the clips.
