Look at your tuck-flap closures - they are incorrect in all instances.
Your tuck flap closures are incorrect in all instances - instead of being a dead split along the lid, they should angle across and then up to capture the slits in the tuck flap (which is also incorrect, should be inset by the width of the card)

We have just plotted a sample of the double tuck flap carton and the flaps are too tight to insert into the box. This is a fundamental mistake guys.
